You don't even need a relay; should be just two diodes.

This Bulldog unit should have some sort of output that makes a ground when the remote starter is on.....it should be already connected to whatever you're using for your Passlock II bypass, right?

You just need to split that output with two ordinary diodes (Radio Shack or wherever).

First, cut the connectiong between the RS82 and your bypass module.

Connect the striped end of two diodes to the RS82's GWR (ground-while-running) output.

Connect the other end of one diode back to your Passlock bypass like it was before.

Connect the end of the other diode to the car's keysense wire.

That or if the RS has a - IGN3 output you could probably just wire KS to that as well.
