Hi all,
Trying to identify this relay its behind the brake booster and has 3 wires going to it, one seems to come direct from the battery.
Any help appreciated.

 

The magic 8 ball isn't working but I'm all-in on guessing today - best to indicate what vehicle you're referring to when seeking answers to questions. It's an A/C Relay if you own a 1969 Cutlass of some type with air conditioning.

 

BTW, the wiring for the A/C is located in the CSM in the A/C section.

 

Thanks, I have a starting point now much appreciated
