Ok so I did my remote start last night in my truck and I got it working the remote start part. I didnt have 3 more relays for the light flash and door unlock and lock so I had to wait untill this morning. So this morning I get up and I go to the store and buy 3 more relays now I drove my truck to the store. I drive it home and then I finish the install. Now the door looks worked for alittle bit a few times by the button on the keychain then it stoped and now that it doesnt work and the remote start doesnt work. So I tried to manually start it with the key and now it doesnt work also. All the lights on the dash come on normally but for some reason the 4wd lights high and low are flashing like really quick flashing. So I tried to start it still and it wont do anything. So I went to the starter solenoid and jumped it from there across the two studs and it started and ran but its in 4wd and I didnt put it in and the lights flash still. So whats wrong with my truck now.. Its a 94 with the 5.0 in it by the way. Is it the starter solenoid? By the way the brown wire off the the headlight park light switch thats for the park lights right. Because thats what I tied into for the light flash.

Well I think I found the culprit a blow maxi fuse. Will have to wait for a friend to get off work in order to get ride to autoparts store.

In my 89 and 90 the brown wire was for the park lights. If that fuse doesnt do the trick I would remove those new relays you put in and try it, see if it works.

Hey NY Mustang 50 I installed one in my 95 xlt and had some problems also I found if you unplug the unit and plug it back in it resets the module I called tech suport and they told me some times the modules have to relearn the programed vehicle also how did you wire the relays for your doors ive been having trouble getting mine to work good luck
