I purchased a Redeye crate engine and it arrived with the needed engine harness. The majority of the connections are made and the finally ones I am able to identify except one. It is on the left side of the engine on the same line as the coil pack connections, located middle coil pack closes to the firewall. I have looked at every possible YouTube video, google images, and even went to the dealer to try and see if they had any Redeye models on the lot. All lead to a dead end. The dealer tried looking up the harness on their system and reading the schematics but as some of you already know, if you’re not coming in with the part number, good luck on getting answers out of them. If anyone could please explain what this one wire lead connects to it will be greatly appreciated.
