Remote stater won't run with AC on?

Not too much to add just I would agree find the tach wire and try that..It isn't THAT hard to find. Sounds like maybe the voltage sensing isn't seeing a big enough increase in voltage once the car is running. I've seen cars do as you mentioned before but that's usually with Design Tech remote starters where you have to cut the in gear loop..Also your clock is probably getting brighter when you step on the brake because the park lights shut off and it goes back to normal brightness instead of being controlled by the dimmer. Good luck

If you cannot find the white wire you can run outside into the engine bay and hit one of the wire (small diameter) going into the ign coil. Then use the tach finder to verify. You might want to just run the wire through the window to see if it works instead of going through all the trouble of running it through the firewall to find it didn't help. I have just installed the same alarm (purchased from ebay $40) and used the wire I mentioned above. Usually I just go voltage sensing but I figured I'd use tach this time. Worked on the first try. Godd luck.

p.s. Installed an autopage 750LCd on a silverado with 2 100+ watt amps and it stoped the voltage sensing from working. If the truck didn't start the alarm thought that it did. My truck has the same engine and voltage sensing works perfectly. Think the amp load confuses the brain. Might be the same prinicple with your a/c Good luck was ment earlier
