Name that Ok so this is my first C4 engine install and I did a pretty good job of marking plugs but this one eluded me. Its an 8\" pigtail goes threw another plug and into the main harness behind the Distributor. 1990 L98. Since I just replaced the coolant temp sensor on my Silverado this AM and the plug looks nearly the same it's got me looking for one that's not on my new engine or on my own. I'm sure it's really simple to somebody in the know.
Ok got it. I'm installing a Superam and had not transferred the sensor yet to the bottom of the Plentum. I assumed that that sensor was one of the plugs up front on the right wiring harness.
Name that Plug !
