This truck came in and had an extremely slow crank. I put the ground on to eliminate a bad ground but mostly because I didn't want to roll around in the snow to look into the factory grounds. I left it because it fixed the slow cranking issue
When your trying to take it off or putting it back on? I had that happen the first time going back in and I had to take it out and thread it back in again till it sat at a different position
Yup I forget what mm but you can take any deep socket and cut a piece out for the connector. Or for the 7.3 iprs where you can separate the electrical you can use a deep socket then out the wires on after
