I'm trying to install my Greddy turbo timer with harness adapter. I plugged in the adapter to the front of the fuse block but I am having trouble with the back connector. Does anyone know what color wires are coming out of the connector or any other way to determine the right connector to get it plugged in. I don't want to have to try every connector one by one. It is a pain in the ass. The fuse block doesn't move that much.
Thanks,
Scott
