adding a switch to aftermarket door locks

So what type of switch would work on the setup in the pictures if any? I guess I we didn't get to that part since it was mentioned the one in the picture would not work.

A five terminal window switch, e.g. Spal etc.

Hi, There is another option which would require soldering to the circuit board. On the trace side of the board where the door lock relays are located there are single pads (circuit board is obviously double-sided). These are the coils of the relays. If you notice, they share a common trace (node). Circuit tracing and/or careful probing with a multimeter will give the polarity at the coils. A single wire soldered to each of these single pads will allow your switch to control the relay, with the switch common connected to the proper polarity. Hope this helps. Mark

I didn't have the courage to suggest it!

Based on the given info, I would NEVER suggest that. Your just asking to fry the whole unit IMHO.

It's okay. I won't be doing that, but I had thought about using a relay socket instead of the built-in relays. I figured it would be more accessible anyway since I was having problems starting my car a while back. I had to replace the brain once before and then it worked again, but now that's why I wasn't too concerned about this unit. Thanks for the switch info...I think I have been getting one too many senior moments and no I am not a senior yet, but I am not in high school either. LOL

I've pulled this stunt on site but I wouldn't recommend anyone bar an experienced installer + DMM try it.

I went to my old bin of parts and found me a nice set of these. The wire says Franklin Electronic Wire 1.25mm Squared. Yes there a tiny two after the dimension and 1994! The red, blue and yellow wire are the same dimension above. The white and black say VSF 0.75mm UNICAB 1993. Yes I bought them around that time if you can believe it. The reason I wanted to put this up here is because I was looking at some on amazon that apparently have smaller diameter wires and not quite in the same places. I knew I had something, but I thought I only had one. It turns out I have a double relay and a single. The double says 7&U UC-3006 TAIWAN. I wanted to put them up here in case anyone else was looking at these and was trying to figure out the colors on the ones with relays I was looking at. I ended up just getting some relays since I had these. Now I can wire a set of relays for door locks. I'm changing the alarm and I will need the external relays for it anyway.

Blue = 30 Red = 87a Yellow = 87 Light blue = 86 and black = 85 although the last two are interchangeable. Don't forget, diode across 85 and 86, band to 86 (+) side of coil.

Thanks! Will do. I have some 1N5819 diodes, will these work? I think they are 1 amp, if I remember correctly, but honestly I don't.
