Plug and play - Headlight Relay Kits
Mark,
Yes, you can still use it. You could mount the relays on the inner instead or shorten the main power wires up and mount on backside of rad yoke, pass side. That would only require crimping on a couple of ring terminals for alternator connection. If you want to mess with the mounting block terminals, they are an open barrel type crimp and should be done with the correct tool.
You could send it back and I could alter it to a new location for you.
Whatever works for you is OK with me. Shoot me a PM if you have any questions.
