Hi,
Im putting a MkiV Supra 2JZ-GTE, ECU ,auto gearbox + ECU and fuel pump ECU into a 1990 Mercedes 300CE.

1. Where can I get some good wiring diagrams to help with the Supra stuff
for help installing in the electrics.

2. How am I going to get my mechanical instument cluster to work with the Supras digital output ? Speedo,rev counter etc

Thanks

Sounds like an interesting swap. You can buy an electrical wiring diagram manual from Toyota, specifically for the year supra you are pulling your engine out of. This is a much more comprehensive reference than what you'll find in the back of the mechanical repair manual. I'm not familiar with the 2jz stuff, but with the 7m's some of the wire color schemes and even connectors change between the years, so be sure to get the proper year.

I think the cluster will be a pain. Coolant temp and oil pressure (if you have oil pressure) will be easier in a way because they're probably analog on both systems, but the sensitivites are probably different. If you had the sensitivites for all the gauges on both clusters, you could build voltage divider / amplifier circuits to correct each one, but the only way to get that info is probably to measure it. I tend to think the same goes for the tach. I think making your mechanical speedo work with an electrical input is more trouble than it's worth. Do the clusters look at all the same? If you could swap the gauges out of the supra cluster and into your mercedes one, and make it look nice in the process, you'd have far less headache.
