Im doing an obd2 s52 swap into my e30. There is a white relay on the passenger side in the engine harness. I don't remember where it came from, either the compartment where the dme was or somewhere by the secondary air pump. It does have the 12+ power wire running from it all the way across engine to the secondary air pump relay though.
I think it may be the unloader relay? X6326? Do I need this for my swap to work? or does the car just use the unloader relay in the e30 fusebox?
**Also there is a ground wire with a lug coming out of the secondary air pump loom. Is this ground wire needed or was this part of the secondary air pump circuit? its on the passenger side as well.
