My new daily driver. 1984 dodge rampage

Tune it up, then set the timing. RN12YC champions gapped to .035, new wires, cap, rotor etc. Fully warmed up, disconnect the 2 wire temp switch, engine cooling fan should come on, and check engine or power loss light will light up on dash, computer is now in "block learn"

Hook up your timing light to #1, and remove rectangular rubber plug on the top of the bellhousing, shoot your timing light thru that hole. Theres degree markings cast into the trans case in this location. bump your timing around to where it needs to be. 1/2" or 13mm wrench is what fits the dist hold down bolt. Once timing is set where you want, tighten the dist bolt down, and reconnect the 2 wire temp switch.

Some years reconnecting the temp switch will make the dash light go out, some years reconnecting the switch doesnt make the light go out, and you will have to shut the car off and restart it to reset the light. My old 87 lebaron turbo coupe, and 88 daytona shelby z were both this way. Not sure if it had something to with the programming of the LM on the 87 turbo or on the SMEC on the 88 z

If you hook the timing light up without disconnecting this switch, your timing mark will not show up on the timing tab, as the computer has the timing advanced like a vac advance would on an older distributor. Thisvis the electronic equivalent to disconnecting a vac advance to time an engine.
