Problems with door locks after installing keyless entry

Well I swear sometimes I'm my own worst enemy!

Today I installed a remote start and keyless entry system in my truck, had a couple of problems which I will describe. Now my driver door unlocks immediately after you lock the door with the lock button (lock button on the door, my remote is not functioning).

When I installed the system, I installed the lock and unlock wires in the wrong order. My instructions were assuming the locks took 12v to actuate the locks, when they actually use negative (gnd) to actuate. I think installing the leads backwards cooked the module itself, so now it has an open ground all the time. It's supposed to pulse ground. So, when it's hooked up it instantly locks my doors. So I unhooked the leads from the module to the locks for now while I get a replacement module.

I just noticed that my door was unlocked, and when I went to lock it, it immediately unlocked. Only the driver door is affected. As stated above, I can use the key or just push down on the lock (not the button) and it will stay locked.

Any idea as to what I did, or better yet what to fix?

Another related issue. My remote start had me tapping into several wires at the ignition harness. There are three 12v constant wires at the harness, two are yellow and one is green/purple. I was using the two yellow wires for two different 12v constant connections. My batteries were disconnected (or so I thought). Turns out one of my negative cables made its way back to the battery and it was live. I shorted the connection at one point while working. Now I have no power to the two yellow wires. What is crazy is that everything seems to work fine. Car starts/runs fine and all the accessories seem to work fine too. I checked every fuse, and none were blown either. The remote start is working fine off the third 12v constant (green/purple).

Anyone know what the yellow wires run, and what I need to do to get power back to them? They were 12v constant (all key positions)

Sorry for the novel, any help is much appreciated.

Happy Holidays!

Thanks

Thanks, if only I had paid a little more attention to that little minus sign after the description of the lock wire

No time to cry over spilled milk, hopefully someone has some ideas.

Gave Up

Well, turns out I couldn't solve this problem. Not sure why, but I couldn't get the Audiovox Prestige unit to operate my door locks correctly. The remote start needed an additional Tach Sensor Module, which was not what I gathered before installing the unit. I pulled it out and returned it.

I like to do my own work, and figured I was up to the task. However, like others have said....unless you really know what you are doing, this is a project that is best left to the pros. There are lots of variables and I couldn't seem to sort everything out.
