I'm trying to troubleshoot an electrical problem around a Bosch type (cube, 5 pin, 30/85/86/87/87a, etc) relay that is buried way up in the dash of my '52. If I could get a meter on the relay pins I could figure it out, but there is no way I can get to it. I could make one, using the female end with wires that ships with the relay when you buy a new one, but no one sells a male end that I can find. I tried opening up a relay and gutting it to get a male end, but ended up destroying it. Does anyone make an actual "extension cord" that has a Bosh male 5 pin plug on one end, at least 3 feet of 5 conductor wire and a Bosch female 5 pin plug on the other end ? Maybe I should go into business making them?
