Putting aftermarket cruise control in my 2002 Z28 and cannot find the VSS or tach feed wires. I don't even know where the PCM is to start from.

i dont know much bout it but when i helped a buddy install an after market tach w/ shift light on my brothers pickup he ran the tach wire straight to the distributor somewhere up in there

Can't really help you, but the PCM is located in the engine compartment wedged between the front edge of the windshield and the inner wheelhouse on the passenger's side of the car. Should be a BUNCH of wires coming out of it.

Capn you had better be damn good and sure of yourself before you go messin with a pcm or an LS1 dis ignition system. It only takes a Nanosecond to blow out a $1000.00 processor!!! Just a word of caution not a Dis.

the vss is in the instrument cluster, there is no TACH wire cuz there is no distributor.

A very helpful person directed me to LS1.com and there under FAQ was the pinout for PCM's of various years. It showed me exactly which pin and which color for both the VSS and TACH wire. Lots of good info there, you should check it out. The cruise control works great by the way. Thanks.
