I installed a GROM USB adapter today in the common spot behind the left seat, when doing this I noticed that there are 3 plugs to the TCM computer which were all unplugged. This is a JDM 1990 manual.
This is not wildly unsurprising in that my traction control has never worked and pushing the TCS switch does nothing... I shed no tears as early 90's traction control has always been pretty miserable in my experience.
I had originally assumed that it not working may be to do with my 1990 having a 2002+ ABS upgrade and thought maybe the wheel speed sensors/signals between these two systems weren't compatible. If it turns out to be these plugs then great, the car is apart at the moment so I can't plug them in and drive it. Before I do I'm concerned though that maybe these were unplugged for a reason and I'll do some damage plugging them in again.... there's the later model ABS and also a bit of a butchered wiring loom with cut wires in the front compartment. I just can't work out why someone might have unplugged these. Does anyone have any ideas?
