2003 Camry LE autostart problems

Help. I've got everything else good. except I blew the alarm fuse due to the Blue/Red (A/C=Heater) wire resting on Gnd! It only registers 12Vdc when ignition is on and the fan is turned in the ON position. This is usually easy one. Looking for 12Vdc thick wire that turns on in accessories position. Did a 2002 Solara before, but don't understand why I'm getting different output from that usual Blue/Red Wire. This is on the right side of the steering column is on the same plug as the WHITE/ red Constant 12Vdc wire.

thanks Chris, I was hoping you'd answer before I came back to work on Dad's car. The fuse blown was the alarms 30Amp! I did not see another Ignition wire in there. I only put the 12V ignition to the BLACK/ red, I did not see a big BLACK / YELLOW for 2nd ignition. The only BLACK / YELLOW that was there was a thinner blk/ylw for 2nd starter-right by the side of the blk/wi 1st starter wire.

Also this engine doesn't have a cable for throttle right? I didn't see one. I saw some 6 wire plug up above by the throttle pedal. any of those wires can be used for the rpm sensing? The BLACK/ orange wire that you mentioned did not work on this 4cyl LE model.

Thanks Chris, you Rock!

You wouldn't believe what was the cause of my problems! A weak battery in my DVM. I couldn't get an accurate reading from the tack wire in the diag plug. I changed it and it was reading much better. Anyways the alarm programmed to learn the tach signal. This LE did not seem to need transponder. In the owner's manual (car), it specified the key had the transponder units in there. Oh well, it works. I also just put a diode in the wi/blu trunk pop wire so that the signal only goes towards the trunk motor. I did not have to 5 wire it. It worked several times, I tested it. Did you find the same? Again, thanks for the help. It's been years since I did an alarm. I was a little rusty here....

DAmn Volt Meter! it was the cause of me not being able to read tach correctly. I replaced the battery and it was much better. it was in the diag plug, like you said. Wheeee.... the tach learn mode confirmed on the alarm. I also found that I only had to put a diode for the trunk pop wire. So the signal would only go to the motor and not to the relay. It works and I tested it several times. Did not have to 5 wire the circuit.

Hey thanks again. Its been years since I did an alarm. I felt really rusty but got Dad's camry done.

sorry for the dual post! the server said i had an error replying!
