so how do the electronic type plug in/connect up???
Requires 3 wires to be connected up, ignition live, permanent live and an earth.
Boost/Vac is taken off (in my case PCV via Forges offering), I ran the Boost/Vac line into the cabin. Small Black Electronic sensor where the Boost/ Vac line connects to (via a small filter) small gauge wiring then goes from the sensor upto the gauge, Small gauge wiring upto gauge for the + and -.
Don't think I took any photos of the sensor and location to be honest, but does this helpGaz?
