Hi
I am installing a viper 5301 in a 2001 Chevy Tahoe and wanted to know if I can get by
Not using a relay on hook ups like the horn honk, factory alarm disarm, and dome light.
These are all (-)200mA from the viper and all the ones I want to tie into on the truck
horn honk, factory alarm disarm, and dome light are (–) is this ok to do on (-) or should I use a relay?
Thanks

you should be okay making direct connections without the use of relays for all 3 you listed.

Viper says to use a relay but i thought since these all (-) that i am connecting to in the truck and the viper output on those wires are (-) that it would be ok? Thanks

You should be fine, the horn honk might need a relay, but only if it is not working properly. Except one question. Isn't the factory alarm disarm for your vehicle in the door? Or is that 2003+?

It says its in the BCM under driver side dash. If this was a 2003 it would all be thru data bus i wish i had the newer computer!! Thanks

Listen, you don't need a relay for horn as it runs to a factory horn relay alread. Factroy disram won't need a relay because it is a simple pulse to turn off. The dome light however will require a relay(if you mean dome supervision) as it is high current negative to the light. ------------- Mike M2

OOppss sorry, dome light supervision, they say in direcwire to use the door trigger for the dome light would this work with out a relay or should i just use a relay and hook into the (-) dome light wire? Thanks Mike!!

Personally i prefer using the domelight wire itself with a relay.
