I have a custom made engine wiring harness, it has every option Speed Scene Wiring offers for Chevys LT1 and LT4 engines. Each plug and wire end has an easy to read location tag for easy installation. It has never been installed, its brand new. It has 2 different MAF connectors, etc. Highly recommend for boosted or NOS applications. This harness runs about $690.00. Was gonna use it for dyno, but I went with a OEM harness for my 94. Shipping in US on me. Paypal accepted.

Thanks, Dwayne
