Progress Thread Pete is checking out these valve covers

That one wire is for power. The clutch grounds itself through the body. You need to unplug the pressure switch and jump it with a piece of wire. Turn the AC knob to on and check the factory compressor connector for 12v. That wire connects to that black wire. Should be black / yellow stripe. The factory connector has a wire that goes to ground instead of grounding at the compressor body.

Looks like its a standard round push in connector. They sell those at all the parts stores in the electrical aisle in all the red, blue, yellow sizes.

Spray a little lube in there and keep working it.

Yep..... that’ll do it!

The compressor should come with oil in it. The system as a whole has to have sufficient oil in it. If you are replacing the entire system you have to put a little oil in all of the components. Some in the condenser, evaporator, and the dryer. You need to know how much the system requires and make sure that what everything adds up to. At least thats how the installations had me do it for the system I installed.

When changing a compressor I always turn the compressor over by hand and drain the oil out into a glass measuring cup. Then I add that same amount in the new compressor. If everything is new I look up how much oil the system takes, pour it in the compressor...hook the lines up and spin it by hand a bunch of times.

The issue with your system is that it isn't a stock unit. There should be something that says how much oil the compressor takes.

If unsure...take the lines off and unbolt the compressor, drain the oil out into a glass measuring cup. It'll show you how much oil they put in it.

I don't usually put oil in the lines but I do lubricate all the o rings. The only line I may put oil in is the low pressure side.

On the ironically named quick disconnects, it’s worth buying the Lisle tools to start with. If you have not used them on the fuel lines yet, you will probably prefer them. At least I found them much easier to use than a couple of other types of tools. Of course, knowing how the dang connection was built was also handy.

I like that AC hose not running over the intake manifold. Some DEI heat shield might still be a good idea on the line and look better than the decaying foam pipe insulation most of us are likely to still have.
How well do the wire separators work and what brand are they? I realized yesterday my nice wires are laid out like spaghetti and I am lucky to not have misfire issues.

That nasty accumulator hose on my non working AC is what prompted me to rip it out. I know that’s taboo on here for a lot of people, but hopefully one day, AC will be back on top of priority list, and I’ll be going through what Pete’s going through.
I had some good luck with two sets of the Ford Racing wire dividers. They got everything set up nicely..... one set was not enough IMO, but still relatively cheap.
