I originally had a tbi 305 in my camaro and put a 350 carb in it now with all the wires still in tack and in the car. I want to convert to tpi this winter. I was wondering if I could plug in the all the wires that run from the interior of the car climate controls etc, to the tpi computer. Also do I need the speed sensor hooked up for the tpi or will it mess up the performance cause its not hooked up, cause my camaro is a 91 with the electoric speed sensor and the tpi i have is off an 87 that uses a speedo cable. Thanks for any help!

the climate contols can be run independent
of the TPI computer.
Also do I need the speed sensor hooked up for the tpi or will it mess up the performance cause its not hooked up, cause my camaro is a 91 with the electoric speed sensor and the tpi i have is off an 87 that uses a speedo cable.
if you have to emmissions devices then youll
needto enable the VSS. youll need a 4k pulse generator
available for cable drive speedos. the output
of the stock carb/tbi is a 2k pulse.
if you dont have to have emmisions.. nix the
input.
if you have a 350c/200/700r4 youll need TCC control.
you can have an external switch for this.
