Folks -
I need help identifying these relays and whether they are original or have been replaced with alternate parts. I suspect the latter for at least one of them since there is a jumper wire on it. See pics below.
This first one controls the headlights. It is located under the dash near the steering shaft. What is the original part number? There is not one on the relay. There is also a jumper wire connected so I suspect it is not original. Wire colors are solid blue, blue/brown and yellow/blue.
Next are two relays on the inner left front fender well just in front of the radiator. I have no idea what these are for. I?ve tried disconnecting various wires and testing for voltages while turning on various systems, e.g., lights, signals, etc., but have not been able to measure any volts. The headlights still work when these are disconnected so not sure what they do. The rectangular one has 4-pins but only three wires connected. Colors are solid blue, white/blue and blue/yellow.
This next one is just below the rectangular one but is a cylinder. Has two wires connected to it. Wire colors are blue/black and blue/yellow.
There looks to be a grounding point just above these relays too. There are 3 or 4 wires connected to the ground. See below.
I suspect a number of changes have been made to the original wiring layout. Any suggestions figuring this out are appreciated.
