Long time no update but we did a lot of work. The mechanical side of the swap is completly done now and it fits perfect I must say.
Now I would need your guys help a bit with the electrical side of things. Because I hate the shop manual for the supra.
We removed the complete front engine harness as 95% of it isnt needed anymore so we will make up our own for the front stuff.
We will put the two front abs sensors straight into the abs ecu.
The three problems we currently have:
1. Progressive Powersteering
As I understand it this has its own ecu which then goes with a two pin connector to the steering box. The ecu gets power, ground and a speed signal. Am I right that it gets its speed signal from the gearbox abs sensor on the R154?
2. Rear ABS Sensor
As we have a TKO600 gearbox the rear abs sensor is gone in the car. Our 89 car has a mechanical speedo which is another problem at this time. We dont want to press any wheels into the driveshaft and mount the old sensor. We've got an electric vss in the tko gearbox that puts out 17 pulses per revolution from I know. I would need to know what signal the abs sensor in the R154 gearbox gives out so we can search for a adapterbox that will convert our signal. As I saw we then just have to hook up this altered sigal to the abs ecu and the power steering ecu.
3. Speedo
Yeah we have an old mechanical speedo.Our gearbox would give us the option to connect this but then we would surely need an adapter gearbox because of the different outputs. Is there a electric speedo for the MK3 in later years Because altering an electric signal is much easier. The second option would be using and Abbot Cable X which converts the electric signal through a small motor and feeds it into the speedometer. Problem here is the strange push on fitting on the speedometer.
Any help would be really nice guys.
