Has anyone out there used the passkey box on their 4.9 swap ? I am wondering if you need the right resistance between the wires that go to the key on the caddy.
I used a pass key box on a series one 3800. The wiring diagram for the module was hard to find. I ended up replacing the module since I tried all of the resistor values available. If you have the key, measure the resistance of the pellet and solder a resistor with the same value between the small wires. If you don't have the key, do a search for a remote starter company called designtech. Their website shows how to bypass the pass-key to install a remote starter. They have all of the possible resistor values. If none of these work you may want to look into an alternate module from west coast as a new module probably costs more than the alternate. I might have a wiring diagram but I'll have to look for it.
Yes thats exactly what you need to do, and before I had a chip burned to turn it off I wired up the box that was in the caddy and put a variable resistor in to match the frequency.
