drift_bear Posted July 20, 2011 Share Posted July 20, 2011 If the mods think that this is in the wrong area then feel free to move it after i done my BPU at the weekend, thought i would do a write up about doing certain things, the main 1 i had problems with was finding instructions on how to do the HKS FCD so i took pics as i went along to help out anyone else and also to follow back incase i done something lol. Only attempt if you are confident with a spanner! Tools required: Phillips screwdriver, 10mm and 12mm spanner, wire clippers, crimping tool. Parts required: HKS FCD (set to number 9 on the FCD itself!) Steps: You need to remove the foot rest from the passengers footwell to expose the ECU. Undo the two phillips head snaps holding the carpet down and pull the carped back to expose the plastic foot rest. Remove it by undoing the two 10mm nuts. You then need to un-clip the ECU pin blocks out from each section, there is a single and then a double ECU pin unit. These can be a pain to do to start with due to the ammount of wire there is down there. Once you get the single connector off it will look like this Once you have that off, if you feel in the middle of the double connectors, you will find a 10mm bolt, un do that and then un-clip as usual Then once these are done you can remove the ECU Once that is done and removed it is now time for the fun part, and that is locating what wire goes where! it can be a pain to do but once you realise which way it sits then its not to bad. All the pins in the ECU are numbered, so you have to look to see them! RED WIRE - Splice to wire marked 'B' on ECU diagram (Either pins 31 or 33) BLACK WIRE - Splice to wire marked 'E' on ECU diagram (Ground) YELLOW WIRE - To pressure signal wire marked 'P' on ECU diagram (Pin 62) WHITE WIRE - To wiring loom side of original pressure signal wire. The wires you need all have male/female connectors on them already so al lyou need to do is unplug them and then use the connectors that come with the FCD carefully splice them together! you can see in the pic below the connector that is unplugged is where the RED WIRE connects to The YELLOW WIRE and WHITE WIRE connect to the pressure sensing wire which must be cut (not spliced). Cut the wire a sufficient distance from the connector block, then crimp on the connectors. YELLOW connects to the ECU side, WHITE to the vehicle loom side. I then put the ECU back together again and stuck my FCD to the front of the ECU (the bottom left bolt holding the ecu to the footwell is where i grounded my BLACK WIRE and used the shell as the earth. Then i started up the car to make sure that it was running right. It will take a couple of mins for your ECU to re-learn its idle point again so dont automatically think that there is something wrong. Once you are happy with it then switch off the car and then start putting the footwell back together again. Quote Link to comment Share on other sites More sharing options...

drift_bear Posted July 20, 2011 Author Share Posted July 20, 2011 Good guide! Not looking forward to fitting my FCD or EBC its not that bad actually tbh, its just time consuming when you first do it lol Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted July 20, 2011 Share Posted July 20, 2011 The wires on my car had no connectors on them.. I think your car had this stuff installed previously. Quote Link to comment Share on other sites More sharing options...
drift_bear Posted July 21, 2011 Author Share Posted July 21, 2011 The wires on my car had no connectors on them.. I think your car had this stuff installed previously. Even if you havnt got connections, if you follow the guide will still be able to wire it in Quote Link to comment Share on other sites More sharing options...
BABZ988 Posted July 21, 2011 Share Posted July 21, 2011 if you've had done it before...lol it wouldn't took me so long to fit mine, but why set it on the 9 number? i didn't found anything so i let it on 6 (me think) and it look to work well Quote Link to comment Share on other sites More sharing options...
Notts_TT Posted October 3, 2011 Share Posted October 3, 2011 (edited) Hi On pic it looks like the yellow and white wires go to same place ???? Also are any of 4 wires unplugged and only run to fcd or are all spliced onto originals. Gotta be sure :-) Thanks Edited October 3, 2011 by Notts_TT (see edit history) Quote Link to comment Share on other sites More sharing options...

np89 Posted September 27, 2012 Share Posted September 27, 2012 Sorry to ressurect, but if im reading this right, am I right in thinking that the red and black wires are simply spliced in but the original pressure signal wire is cut and the white wire is joined to the loom side of the pressure wire and the yellow wire is joined to the ECU side, so the FCD is effctively a "bridge" betweent he 2 sides of the cut pressure wire (assumedly to intercept the signal, aler it and feed it to the ecu))?

st3ven1 Posted September 27, 2012 Share Posted September 27, 2012 Might want to read post 11 of this thread as it appears the FCD wasn't correctly installed in this guide. Quote Link to comment Share on other sites More sharing options...
np89 Posted September 27, 2012 Share Posted September 27, 2012 can anyone confirm this is the case? and what was wrong? Quote Link to comment Share on other sites More sharing options...
Caesard Posted September 28, 2012 Share Posted September 28, 2012 Did mine using this guide and it is still hitting fuel cut. Quote Link to comment Share on other sites More sharing options...
Marty Posted September 28, 2012 Share Posted September 28, 2012 Did mine using this guide and it is still hitting fuel cut. You can adjust the cut on the hks fcd using the pot in the middle(under the sticker). There is a guide for fitting the fcd here too, bit more simplified... http://mkiv.com/techarticles/fcd/fcd.htm Quote Link to comment Share on other sites More sharing options...
ashbuster Posted September 28, 2012 Share Posted September 28, 2012 (edited) fcd looks like its installed right to me this is basically it RED WIRE - Splice to wire marked 'B' on ECU diagram (Either pins 31 or 33) BLACK WIRE - Splice to wire marked 'E' on ECU diagram (Ground) YELLOW WIRE - To pressure signal wire marked 'P' on ECU diagram (Pin 62) WHITE WIRE - To wiring loom side of original pressure signal wire. just need to make sure the ecu pin outs are the same but either way still cut the pressure signal wire and splice the power and earth Edited September 28, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...

st3ven1 Posted August 23, 2013 Share Posted August 23, 2013 Take it the Thor FCD is wired in the same ? Yup, there is some handy diagrams in this thread that show exactly where to wire everything and the colour of the wires. http://mkivsupra.net/vbb/showthread.php?269719-Thor-VFCC-FCD&highlight=vfcc Quote Link to comment Share on other sites More sharing options...
Big Supes Posted December 31, 2013 Share Posted December 31, 2013 It might be worth noting this guide is for jspec cars... as I have found out with an array of warning lights. Apparently I need to find the fitted guide for a US Supra, but can't seem to find one anywhere. Does anyone have any links? Quote Link to comment Share on other sites More sharing options...
shaz2010 Posted April 3, 2014 Share Posted April 3, 2014 (edited) Bumping this as I need to install my FCD to my supra uk, is the wiring all the same? Edited April 3, 2014 by shaz2010 (see edit history) Quote Link to comment Share on other sites More sharing options...

Fizzy T Posted July 27, 2014 Share Posted July 27, 2014 So the Jspec and UK spec fitting instructions are the same? Tempted to fit mine tomorrow and don't want to get it wrong. Quote Link to comment Share on other sites More sharing options...
shaz2010 Posted July 28, 2014 Share Posted July 28, 2014 Yes mate I wired mine in and all is good, Straight forward. Quote Link to comment Share on other sites More sharing options...
