Here is a question i have not yet found an answer for.
I have a viper 550ESP that i will soon be installing in my roadmistress wagon. One of the Items added to the alarm system will be a 450t multi channel adapter. I am trying to reduce the number of un needed relys.
Rather than add a redundant relay, i would like to hook my dome light supervision wire from the 550ESP AND my channel 6 output from the 450T to the same (dome light supervision) relay terminal #85. I dont see why this shouldnt work and dont think it should even have to be diode isolated.
Anybody have experience with such a thing?
If it can be done, i would also like to do the same thing with the ACC or ACC2 output on the remote starter and channel 5 of the 450T to allow me to use the car in ACC mode without the key in the ignition.
thanks for any answers.

If your system moves you physically and not emotionally, you have wasted your money.
1993 buick roadmaster...... the seats are leather and the tires are General if that helps.

Yes, but you should still use diodes, especially from the alarm's aux outputs to protect the alarm.
You will need a relay from the 450 to drive the ACC.
And again a diodes at least across the relay coils will be required to prevent on rush.
Thanks for the response but I dont think you understood my question totally. I am wanting to NOT use a relay specifically from the 450. I want it to tie right into the same wire that the 550 does on the DLS relay. Since these wires are "dead" when not in use, the diodes dont seem to make sense. Even if they were both activated i dont see how they would"care" one way or another.
Thats why i asked if anybody had any "experience" doing this specifically.
Installing car alarms and car audio for all these years and it really never dawned on me to try to do this. Customers were paying for needed relays and I wasnt thinking enough outside the box so I never considered trying it. Once I saw all of the relays the roadmaster install was gonna need, i wanted to simplify it a little.

Yes, but connect a series diode from BOTH modules to the relay. That's to prevent one module powering the other's output etc.
Since both modules are only neg triggers and dont present pos signals at any time, diodes should not be needed.
When you see DEI telling you to use diodes in most cases, they are trying to keep a device from falsely triggering through things like an ignition circuit that is off that would show as good as a low level ground for such a device.
I found a couple old alarms in the garage. Im gonna try my idea on one of them and see what happens. My idea might just go up in smoke ....or SPARKS!
