GM OEM door locks

I installed a set of OEM lock actuators in my 1998 Pontiac Sunfire. The donor car was a Pontiac Grand Am from around the same age. All I was able to get was the left and right actuators. The relays and switches were already gone. The actuators have two wires going to them (Blue and Black). I assume that they are reverse polarity actuators.

I plan on using an Ungo MS200 alarm for keyless entry. It has a negative pulse lock and unlock.

I wired the relays for a five wire https://www.the12volt.com/doorlocks/page3.asp#5w and the actuators / reverse polarity https://www.the12volt.com/doorlocks/page3.asp#arp

I used the actuators / reverse polarity first and as soon as I put the fuse in it blew…

I rechecked the schematic and I had everything like the schematic. So I tried the five wire, same thing…

When I unhook 87a from both relays it does nothing, when I hook them up it blows the fuses…

What do I need to do?

I don’t want to use lock switches on the car just keyless entry.

Thanks, Maddox
