Fitting a Thor SLD, Problems.


LuxobargeTT

Recommended Posts

Hi all hopefully someone can help, I have searched, but couldn't see posts with my probs.

 

The car's a 92 Aristo TT, and has had it's speedo converted but not delimited.

 

I recently brought a Thor SLD of a member, and fitted yesterday afternoon.

 

Wasn't able to drive it till yesterday evening, and when I hit 60-70 the engine light came on, then followed by a flashing O/D light.

 

Through searching, I see the flashing lights is commonly due to a dodgy conversion or delimiter.

 

Could someone confirm my wiring is right??

Yellow wire----cut ecu pin 2 wire, leave loom side unconnected and join ecu side and yellow together

Red---power (i connected to pin 1)

Black----earth (i connected to ecu mounting point)

 

I've redone all connections, and took it for a drive earlier, and just the engine light came on, but puled over quicker this time, then put all back as stock and no problems.

 

Does anyone have any ideas?? could the SLD be knackered??

Could fitting this unit be causing problems with the speed converter?? (was fitted before I brought the car, and presumably the wiring for that is behine the dials)

 

Thanks in advance.

Try and search up how to extract the diagnostic code and what they mean from the ECU. The speedo conversion shouldn't affect the delimiter and vice versa. The light you are getting sounds like its the No2 speed sensor loss of signal. To ease your mind it doesn't do the car any harm. If you have cut the correct wire into the ECU and you definitely have a good power source (where did you take the 12 volts from out of interest as the aristo speedo head is completely different to the supra one) then the evidence is pointing to the box itself.

 

Have a peek here to see the pictures of when I did mine. (be an idea if I posted the link lol)

DB, I was following your pic on the LOC, I'm ahh aristo on there.

 

I connected the yellow wire from the SLD to the ECU wire you show, took my power from pin 1 on the ECU, (ignition switch) and grounded it to a mounting point.

 

I have left the speedo head alone, as it was already speedo converted.

 

 

Thanks to the instructions Mas uploaded (thanks very much, really apprieciated) I've just removed the speedo head to find out it's completely different to the supra as you say.

 

Was going to ring Thor, but think they'd be closed now.

 

Would be really greatful if you could tell me how you connected yours, including which colour wires from the SLD went where.

 

Thanks all for your replies, cars currently, carpets up and speedo out :blink:

OK mine was the combined box ie delimiter and converter so I'm not sure what the situation is with the box that just delimits. You can take the 12 volts from anywhere to feed the box for diagnostic purposes if you don't have a multimeter. If you have a multimeter check to see if there is a voltage across the black and red. The feed out the line that goes to the ECU should have a voltage out which will be a variable one, if there is none there at all and you have 12 volts in than the box is duff. If there is a voltage theres no guarantee its serviceable as the box works on a modulating frequency (thats my get out of jail bit lol).

For the record Tom is ahh aristo on this forum but uses his reg number on the lex forum :)

My firm guess is no power to the box, that said these boxs once used dont take too kindly to being powered down fully like when the battery goes flat. If you prove power supply and you have fed the correct line into the ECU then call pete at thor and ask if they can re-program your box.

 

Oh BTW it is a mk1 aristo and not a mk2 isn't it??? I ask as for some reason delimiting a mk2 needs a replacement ECU not just a magic box.

TBH I don't know if this box is just a SLD or a SLD and converter, it looks as though it's had the green wire and yellow wire used, as was previously fitted to a supra, does that give and clues??

 

 

Yep it's a MK1.

 

If it's a SLD and converter, can just the SLD be used??

 

Can you remeber what wire went onto the ECU?? yellow or green??

 

 

Really apprieciate the help, I don't get to use it much, so really getting on my nerves as I've got the weekend off, probably stick it all back together I think as it currently looks like this

MMMM OK well not wanting to upset or anything but that is the best example of dodgy looking wiring I have ever seen. I hate them scotchlocks they are cheap and nasty. i can just see your ecu and it sort of looks like you have a scotchlock on your purple wire into the ECU. Try replacing that with at least a crimped on butt joint. WTF is that massive yellow wire???? Thats one big arsed wire BTW.

 

To be hugely honest though I would have every one of them scotch lock joints replaced with proper joints mate.

You can't remember what wire goes where then???

 

 

Not a fan of scotch locks either, but all are good connections, and it's just a temp thing.

 

The yellow wire isn't a wire, it's a protective covering for some wires, looks stock.

 

Phone call to Thor on Monday I think.

 

Cheers for the help.

Well that yellow wire wasn't on my car lol. The pictures on LOC show you where the wires go for the delimit and speedo conversion. If you were close by I'd take a look at it for you. Green is going to be the speed input and yellow the output from the box if I remember rightly. Typically I can't find the damn page I think its gone now. I do have a copy on a hard drive I removed yesterday. I'll refit it later on maybe. Tom AKA ahh aristo on here should have a hard printed out copy with the paperwork I gave him.
