Doing remote start (DEI Python 871) in '95 Celica 2 door ST. When finished, realized while remote start was running, the radio was on but not the A/C. Put the key in and turn to run position and voila, it comes on. When testing the wires, I realize my pink/white (second ignition) isn't putting out any juice. So, to solve it I ran a jumper between 1st and 2nd ignition wires on the relay pack (Pink to Pink/White). Problem solved. A/C comes on with remote start and all is well. So now the question: will this do any damage to the vehicle or the alarm? Should I use a relay or is the relay pack from the alarm gonna do the job? I've been told it's half a dozen of one or six of another. Help me settle this debate!!!!
Thanx
------------- BOOSH!!

Always use a Relay to split Ignitions from the R/S if the R/S does NOT have Relays for all the Ignitions you need ( 1, 2 , 3 , 4, & Accessory 1, 2, 3 etc. )

A seperate relay would definately be advised. Did you jump the main output wires, or the thin signal wires to the relay pack? You might be able to get away with jumping the thin signal wires if the problem is that the relay isn't getting a signal to turn on, rather than the relay itself being bad. You would run the risk of overloading the transistors or whatever they are using to activate the relays though. If you jumped the main output wires after the relays, what you did might never cause any problems, but it's definately not the preferred way to do it. Once you jump them like that you have just increased the OEM fuse rating by about double since they are normally on seperate fuses. If something should short out there's a higher chance of doing more damage before the fuse(s) blow. You also run the risk of overloading the relay from the remote start and damaging that as well.
Summary: Add a relay.

There is no debate, use an additional relay when adding additional ignition/acc wires.

Ok, mo12v posted that Always use a Relay to split Ignitions from the R/S if the R/S does NOT have Relays for all the Ignitions you need.
On this alarm, the output to the constant, ignitions 1 &2, acc 1&2, etc. are coming from a heavy duty relay pack and are all 10ga. wires. So, if they are coming from a DEI relay pack, is it OK to do this? Not that I'm not going to fix this, but technically aren't both ignition wires going to the same circuit in the end?
