Thanks Scott.

For sure am putting ECM under rear seat. Already have a hole leftover from the gas heater for wires to run through.

I didn't know Vanagon (post '86) had *heated* O2 sensors.

I guess I could run wires forward for relays, but they should be fine in the engine bay. If I had any doubts about crap getting in the relay box, I sure wouldn't put them there! --- :^)

Neil.
