Rewiring my '72 with a Painless Harness

My first of many roadblocks; any idea how I can remove the ignition switch connector? It's wedged between the top of the steering column and the bottom of the mounting bracket.

I've got the entire harness disconnected except for this one connector.

I've got the lower supporting bracket removed but can't figure out how to lower the column to get enough separation to unplug this particular connector.

Follow the column down to the firewall, there is a plate with 3 bolts attaching it to the firewall. remove these bolts which should allow the column to drop down a couple of inches.

Perfect, thanks. Mine had a plastic shroud around the base that made those bolts inaccessible. I ended up breaking it off (it was quite fragile) and was easily able to undo everything. There were five bolts on the firewall and another two keeping a couple brackets around the column.

I've got the entire old harness out and have drawn out my own schematics of that harness to try and compare it with my new harness. I have the 21 circuit Painless harness (10101) which I've found is very streamlined, which is not necessarily a good thing. It doesn't have a bulkhead connector so I'm trying to teach myself where everything goes because the Painless instructions are less than ideal. A few pictures or drawings wouldn't kill them. And I'm coming from a position of just about zero experience with automotive wiring.

So, next question is where does this maxi relay go? I know it connects on the 10 ga. red wire between the fuse box and the starter solenoid, but should I just find an open spot on the firewall to mount it to?

You can mount it wherever room permits. But the closer you can get it to the solenoid the better, that way you only have a small length of wire that is not fuse protected and the long length of wire to the fuse panel is protected. A lot of cars in the 80's and 90's used fusible links, which was a special short length of wire that would melt in half instead of a replaceable fuse. And the fusible links were usaually attached right to the solenoid.

I know this is a little late but American Auto Wire kits have excellent instructions and bulkhead connector that fits in the stock location.

I did one Painless, it was the computer wiring for an L29 fuel injected big block, not too bad had decent instructions. It was the only company that sold one for that engine. I have installed four AAW complete kits. A 57 Chevy, a 67 Nova, a 64 Barracuda (using a 1st gen Nova kit) and my Chevelle wagon.
