Ok so my only real question is I have a complete 1991 speed density 305 TPI, engine wiring harness and all.

So is my dash wiring going to work with the TPI harness since this car came with the 3.1 V6 or am I going to have to find a matching dash harness as well?

Ok one more question. Is the engine wiring different for the pontiac and chevy? so say the TPI came out of a bird am I going to run into wiring trouble when hooking it up to my dash harness in my camaro?

Thanks

 

90-92 TPI and V6 had the same dash / chassis wiring harness.

 

Well thats great news then. This swap shouldn't be to hard.

Ok got another question. Lets say I swapped in a transmission from a pre 1990 Camaro. They used a cable drive for the speedo where the 90 and up Camaro's used the electric drive. Can you upgrade the older models to the electric? Are they the same size and interchangable?

Thanks
