Default Need help please vats
I just bought a base 1990 with no key. I replaced key ignition. Bought resistors to bypass vats. The issue I am having is the 2 wires on harness side going to ccm/bcm for vats sometimes shows resistance.
The real issue is I can bypass with a resistor and when I use multi meter it shows 0 when I remove resistor gives me proper reading. Why would it go to 0 when I install on 2 wires for vats bypass?

I think the starter enable relays tucked under the driver side dash. It might be a large gauge green to large gauge yellow you need to jumper.
