    HI,
    I'm in the process of painting the engine and engine bay of my '72 Skylark 350-4 and when I was moving the wire harness one little wire the goed down the the transmission came unplugged. I haven't had the time to crawl under the car to see where it came from but the plug looks to be in good shape and not broken. I'm hoping when it came from is ok also.

    Question is am I in for a hard time to reconnect the plug and is it hard to get to?

    Thanks,

    Brad

    If the car is jacked up its a piece of cake on jack stands. Asuming your good at putting it in the hole

    The only electrical connection on a THM350 would be for the transmission controlled spark advance emissions control device. I would eliminate that, the engine will run better without it. If the transmission is a 350C, there is a connection for the lock up torque converter, that would be a multi wire plug. You would not have that on a stock 72 car though.

    Ok guys I'm new on here so... I took my motor off and painted it etc... Cleaned engine bay n stuff. Made it look pretty!! When I put everything back together and tried to start the car nothing happened?? I hear clicking . I got good ground good batt. But I do have a question does the starter on have to have 2 connections or 3? I hooked up the main power from batt n another one coming from wire harness. But there's a connection on the starter that remains ?? I didnt take pics so I'm not sure which wire am I missing . can u guys help out. Oh and Also the coil only has a red n black wire right? No yellow? Thanks in advance.

    The starter solenoid has one big connection and 2 small ones. The big connection is the + battery cable and the 2 main feed lines for the entire car. The 2 smaller connections are the solenoid activation wire (purple) and the resistance wire bypass (yellow) The yellow wire is only necessary when using points and some aftermarket electronic ignition conversions. The solenoid connections look like this,

    The yellow bypass wire is explained in this thread,
