Jellybean Posted July 25, 2009 Share Posted July 25, 2009 (edited) J-spec wiring harness wire colours and positions on the harness are the same?? im looking at an article here and they dont appear to be matching http://www.mkiv.com/techarticles/bcc...nstall/bcc.htm Just confirmed with Japanese instructions,not applicable to JSpec Wire locations on the ECU pins are different Edited July 25, 2009 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
Jellybean Posted July 25, 2009 Author Share Posted July 25, 2009 (edited) With some help from google translate and the Jap instructions 赤 -- Red wire 黒 -- Black wire 緑 -- Green wire 白 -- White wire Based on the diagram and counting the pins I will give it a go, thats about as good as my Japanese gets Looks like article is no good for Jspec,different pins. The amount of wires in the ECU is nuts. They would give an asprin a headache Precison Adjust of Volt I have also set the BCC to peak voltage output of 4.3 V as I have a 93-95 car 1. The Connections for Voltage Tune assume your BCC is uninstalled. To Volt tune after the BCC is fully installed, you will need to disconnect the BCC's green and white wires to proceed, but may leave the red and black wires installed. 2. Red BCC wire to any 12V source such as car battery + 3. Black BCC wire, and negative probe of your voltmeter, to ground of same battery. 4. White BCC wire to any automotive voltage source of 5-12V. Simplest is to use the 12V source same as red wire. Others have used the 6V output of a battery charger, doesn't matter because any Input of 5-12v to the BCC will give the same Output for a given adjustment screw setting. 5. Green BCC wire to the positive probe of your voltmeter. 6. Turn screw to provide voltmeter reading of Nearly but Not More Than: 4.3 V for 93-95 cars; 4.1 V for 96-98 cars. This a condensed version Pics and more details is in the Article, article is not applicable to JSpec (confirmed with Jap instructions) not too sure about UK http://www.mkiv.com/techarticles/bcc...nstall/bcc.htm Edited July 25, 2009 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...

Jellybean Posted July 25, 2009 Author Share Posted July 25, 2009 Is this a question or information? It started out as a Q but I found out the answers myself, at least I think I did Ian can you have a look at this thread too for me, she only goes to 0.6 bar after BCC install http://www.mkivsupra.net/vbb/showthread.php?p=2455008&posted=1#post2455008 Quote Link to comment Share on other sites More sharing options...
