Ok I am in the process of working on being able to offer complete ready to go LT1 swap harnesses, this would simply bolt to the firewall on the drivers side (C100), connect to the connector under the dash (C207) and from there plug into your existing sensors on the LT1, put the PCM into the dash in the stock location, and retain all of your stock gauge functionality without spending hours / days of your time cutting splicing and hacking the stock harness for a semi-acceptable fit.

I need to know how much interest in this there is, it seems like for some they stay away from the swap because they are afraid of the wiring and other custom work, I feel strongly a lot really dont know what they are missing out on especially for a HP / $ mod when it comes to retaining EFI, and also the ability to pass emissions.

I plan to offer this two ways, the first which hopefully i'll be able to offer sometime in June would require you to send me both harnesses, for the connectors, it would have all new wire and pins, this would be a one piece custom fit harness, good luck finding a better fit, pricing for this I hope to have somewhere around 450, maybe a tad higher maybe a little lower but shouldnt be a problem keeping it sub $500.

The second would require nothing, ready to go in stock harness for your car, just place the order and it ships out, pricing for this I believe will be around $700.
