I've been updating my electrical wiring and adding microcontrollers to give my El Camino some modern features. I replaced the door lock/ unlock relay with modern bosch style 5-pin relays. I created a diagram and attached it as PDF. The OG relays are a bit harder to find, and when you find them, they are expensive. I hope this can help someone save some time and money.

I pulled the brown and gray actuator wires, the orange-black power wire, and the blue and black switch wires from the original relay in the passenger side kick panel into the glove box area.

I removed the glovebox and mounted the relay to the body to the right of the glovebox. There's plenty of room to open and close the glove box.

Thanks for sharing your knowledge on this upgrade. I am in the final stages of swapping from manual to power windows and door locks so this really comes at an appropriate time. Where did you get your relays? Name and/or brands? Thanks!
