As it was delivered. Park works fine so I'm not sure why all the blocks were needed, ha!

The previous owner gave up trying to get it running right after throwing parts at it. He tried fuel pump, coil, distributor, IAC. Symptoms were very hard starting and no start at all when hot. i quickly noticed there was no 5V getting to the TPS, MAP, or EGR sensors so I pulled the PCM to see what was up. This thing has been very wet!

Two capacitors had a severed lead due to corrosion. One resistor was open due to corrosion as well.

I dug around in my parts bins and scrapped together some replacement components and also fixed one trace that was open due to corrosion. Eureka, she runs! I had a code for MAP sensor which was because its vacuum line was tied to the A/C recirc. actuator instead of the manifold. No wonder they couldn't get this thing running right.

The interior is in pretty nice shape other than the rear headliner and the faded carpet that looks and smells like it's been getting wet for awhile.

Looking good on Alcoa wheels and BFG 33's

The PSOM LCD was in bad shape so I swapped it with the LCD from a 93 Aerostar cluster I got from eBay.

So much better with the 93 Aerostar LCD!

93 Aerostar PSOM logic board. Same part number and logic number as the Bronco board. I only used the LCD but it appears this board would work if yours is toast.

93 Bronco PSOM logic board. Looks to be the same as the 93 Aeorstar board. In fact, the whole cluster assembly looks nearly identical except mine has a tachometer and the Aerostar transmission indicator has an extra D spot whereas the Bronco has PRND21.
