Title: Pressure switch?
Post by: Fairlane514 on April 23, 2012, 08:21:45 pm

Just above the oil filter on the adaptor is a pressure switch with two male spade terminals. The plug that plugs into it is making contact with my newly installed shorty header.
Is this a low pressure warning light? Can I unplug and then loop it?

 Its on a 84 with a Goodwrench 350.

     I am not positive, but is that your oil sending unit for the gauge inside the cab.

If it has pink and blue wires connected it might be for the electric choke heater on the carb.

Edit:
Can you use an angled fitting to gain needed clearance, then use heat reflective loom around the wires, connector and switch?  Or, maybe, relocate the switch next to the distributor at the back of the intake manifold and reroute the wiring.
