Update - The loaner MS was bad. LOL. This was one that I got in trade, then traded it away for powder coating. So, I gotta fix this thing that isnt even mine and gets me no closer to driving.

Same buddy has another bad one (which is why we made the trade) and we are going to send both off for repair and hope that we can get our buckets of bolts running again.

Working on cars is fun!

Hey everyone,

Car has a lovely layer of dust and bird sh!t on it from the stupid little birds that I cant keep from nesting in my shop. My annual wood sale is in a few weeks and that should provide funding to buy a new computer to get the car going. . . Finally!

In the mean time, I have been working on getting AC in the bronco. Apparently, all of the parts from a 98-02 Crown Victoria fit perfectly in an OBS, compressor is from a later model F-150. The only part I haven't figured out is the wiring. I found a thread from a while back that @Mustang5L5 replied to about diodes - Can I just splice a fox harness with the diode into my new harness and call it good to run the AC clutch?

Currently have all the major components installed, waiting on an adapter for the compressor before I can install the lines. This is relevant to the fox crowd also if youre doing a coyote OR I think it would be cool to do a low mount AC somehow and get the lines out of the way. I was planning on selling it but with diesel headed north of $7/gal it makes more sense to drive this thing since it runs on 87 and gets decent mileage.

Evap core installed - same size, just different fittings

Compressor is pretty much the same

Condenser Mounted in front of the core support. Its big.

You just need an A9L?

For the Mustang? No I’m going with another megasquirt based computer. Should probably go Holley by now but the MS is what I know

Nope. Don't overthink. I always recommend choosing the tuner that knows your hardware. If you know your hardware, even better!

Any thoughts from anyone on the AC diode on the bronco?

General karthief · Sep 22, 2026

Not sure if this helps but the Dump Truck has a hydrolic pump similar to an AC pump, the electronic clutch clicks on/off just like the AC compressor and has a diode between two wires, been a while, I know the diode is directional and the reason it was added was because they found the clutch on the pump would engage intermittently and a engine driven hydraulic pump should not be engaged above 1500 RPMs.
You may get some info on how to hook it up from looking at hydraulic clutch pump wiring diagram.

What year is the Bronco?

I'm done flipping through this thread to try and find it.

This I think, is the part number for the late models: https://www.fordpartsgiant.com/parts/ford-diode-asy_f5tz-14a604-a.html

Right! So, when the A/C clutch clicks off or opens, the permanent magnet and rotation act like a generator. The voltage generated likes to power the clutch coil [closed].

What year is the coyote swapped into it?

2015 - aka Gen 2

Yes you could use the fox diode or even a universal one from Amazon. I have done a holley install using the fox wiring for the ac wiring , a painless harness , and I just did a G body monte and used a universal ac diode and tied it all in to the factory stuff and it worked like a charm.

Few ways to do it , any of them will work but the fox stuff for sure will work

I picked up a basically new microsquirt today for $350. So, that should get me running on the fox. Just need to find the time to jack with it. Ill be out of town the next week or two for work... Either way, Im happy with the deal.

Wife doesnt know I spent the money but this was an ask for forgiveness situation!

Proof of life photo. Hope to have some updates soon, this weekend is my annual wood sale which is my fundraising event for car parts.
Rolled the car outside this weekend to do stuff in the shop

hoopty5.0 · Oct 26, 2026

I plugged in the new MS, wired in the BAP sensor, plugged in the wideband. It's basically ready to run. A buddy sent me a revised tune for the micro.

And...

I havent had time. This weekend was my wood garage sale (aka where I make all my play money) and it literally took ALL weekend. If I cant get to it tonight, itll be next weekend.

One day, itll run, I swear.

Well it ran, kinda. It's the same tune that was in it but its dead lean now. I suspect that I had overcompensated for the broken computer previously.
I'm all outta megasquirt skillz so Ive enlisted the help of a buddy. I sent him a data log, waiting to see what he sends back. But... progress?

until then- mini split update? lol
