Hello Steve

I personally have not seen a company that makes an aftermarket harness that includes sensors. Painless makes an excellent aftermarket harness for the TPI setups, and when you order, you can have them personalize the length of the harness so you have some freedom to mount the ECM wherever you'd like. I have seen some people sell custom made TPI harnesses with sensors attached on Ebay, but like the Painless aftermarket harness, they usually are in the $200 + price range. I personally completely dissassembled my TPI harness, and rewired it removing some emissions wires, fixing broken connectors, and adjusting the harness so it would mount nicely into my truck. So far I have about 30 dollars into the harness for connectors, solder, and shrink wrap for sealing the connections. You'll need wiring harness which can be found at ChevyThunder to figure it all out, but it really isn't all that tough if you have some patience

I'm pretty happy I took my harness down and rebuilt it, it gave me the opportunity to rebuild it as an 86 harness to work with the '165 ECM I bought, and it also taught me gobs about how it all worked together, what systems were directly connected etc.
