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

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+?

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.

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