Hello all,
I have a 1990 Toyota Pickup with no engine (3VZE originally) and many wires have been gutted. I am trying to install a Chevy V8. Pretty good so far, but I'm stuck on the oil and temp gauges. Out of the instrument cluster (SR5), within the blue plug, the oil gauge wire is yellow w/ blue stripe, and the temp gauge is yellow with green stripe. I have traced the wires to a plug on the passenger side where the ECU was. I have Toyota sending units threaded into the chevy engine.....can I run a wire directly from each sending unit to their corresponding wire at that plug? This would seem to be essentially wiring them directly to the instrument cluster.
Thanks for your help!

 

Should be able to. The temp sensor wire you are going to want to use is the one wire gray plug. The green sensor (green on my 89) sends temp info to the ecu and won't be useful to you. The oil pressure sender should work.

One question though. Why you want to put that nasty thing in a perfectly good truck?

 

1. Engine was free
2. For the horsepower
3. For the simplicity of everything
4. For the hell of it

Thanks for the info!

 

As long as your sensors will work with what year cluster you are using they are not the same
