Since you asked and I didnt know where else to put it so you'd see it UTFball, here's some info on my TBI swap. Mostly copy/pasted from a post on fullsize bronco, I've got a post about it on Ford Truck Enthusiast too, name is the same on all the sites if you want to search.
I got the holley adapter plate from jegs that allows you to put a gm tbi on a 2 barrel intake (had to machine it slightly so it would fit on top of the egr plate). They have a plate for 4 barrel intakes too. Im running a 89 bronco frame mounted pump (E2000) to feed the engine and a low pressure pump which feeds a surge tank that the bronco pump pulls from (you can google gas surge tank for ideas on how to set that up), but you could just get a newer style (93+) tank with the high pressure pump in the tank and get it to fit so you dont need the surge tank. The surge tank or in tank pump is needed on the old tanks since they have no baffles inside if the fuel gets below 1/4 tank and you go around an intersection the engine will die out until the pump picks the fuel up when it sloshes.
The TBI units regulator drops the bronco pumps pressure to the requred 13 psi and returns the excess to the tank. If your going to use a high pressure pump like that make sure the return line is the same size as the pressure so it doesnt back up. I have used a holley blue electric pump on stock tbi also on a friends jeep so that is an option too.
I put the computer under the dash inside the truck. Im using a 88-91 gm fullsize truck computer from a manual trans truck with a 350, since i have a 351m and a 4 speed the prom is an ASDW. The harness came from a wrecked s10 blazer with a 4.3 in the junk yard (the harness is pretty much the same with the 4.3, 5.0 and 5.7 engines). The thottle body needs to be from a 5.7 truck as well as the sensors (coolant, knock, esc module, etc.)
As far as triggering the system Ive got the gm coil firing my stock 351M distributor. I took the ignition module out of the chevy distributor and mounted it on a piece of steel on the firewall as a heat sink. Where the gm pick up hooked up to the module (two wire connector inside the dist. cap) I hooked those wires to the purple and orange wires coming from my duraspark dist. Purple goes to the P terminal and orange goes to the N terminal. Now the ford dist signals the chevy module which signals the computer. The timing, idle and fuel are all controlled by the gm computer. Youll have to lock out the weights in the duraspark distributor, I tack welded mine, and unhook and plug the vacuum advance can.
Im running the vehicle speed sensor from a 88 bronco as well as the speedo cable. It will read 4 times faster than you're really going, but I noticed the idle is more stable and its less likely to stall when crawling with it hooked up. The early 7747 tbi computers do not have a speed or rpm shutoff so it wont matter if it thinks youre running 100 mph at 25
It fires up after sitting for weeks by the third revolution, idle smoother than the stock carb and doesnt die on hills or rocks off road. Ive got about 500 in it total. Sorry for the long post, but if you decide to do it you can pm me or start a new thread and Ill try to help you out.
Ill post some pics from my phone in a few.
