ebinmaine 79,964 #126 Posted Sunday at 05:26 PM Notes: To get full vehicle voltage to the HEI distributor, this white/blue wire can be used to feed a relay that sources off the ignition switch and uses a jumper from the battery directly to the relay.

ebinmaine 79,964 #128 Posted Monday at 11:58 AM (edited) More of my own notes for the removal of the computer and wiring for the new HEI. Credit to Ford Truck Enthusiast. The following two pics are NOT from the same post. Different vehicles and information. Possibly both helpful to me in different ways. On the "Hot out to Coil" - the HEI distributor will need only one. It MUST be full voltage. Test each wire to confirm. ALSO CHECK: White/blue striped wire. That was originally connected to my own coil, computer, and distributor. Edited Tuesday at 06:58 PM by ebinmaine CORRECTED INFORMATION Share this post Link to post Share on other sites
adsm08 4,866 #129 Posted Monday at 05:53 PM I installed one of those HEI distributors in my mom's Mustang with the 5.0. It had a distinct lack of key-switched power sources, only a single one in fact, where I needed many. I grabbed a fuse block out of an 02-07 (old body) Taurus and used it to get multiple power wires. Hook the main bus to the battery, ground all the relays, and hook the relay control input to the single key-switched source. This provided 7 key-switched power sources, good for up to 30 amps each, off one that was originally rated for 10 amps. I used one to run the HEI distributor, with no issues so far. 1 Share this post Link to post Share on other sites

I should say, there are other cars that can donate their distribution blocks for this setup. That generation Taurus just happens to be plentiful, and the block is easily accessed and removed. 1 Share this post Link to post Share on other sites

I'm leaving the clutch fan in place for now but it's a future possibility. Gains are realized in HP and MPG. Share this post Link to post Share on other sites
c-series don 12,246 #132 Posted Monday at 09:35 PM Years ago there was a local Ford dealer called Plitt Ford. I was in the market for a new car for my wife so I went and spoke to a salesman. I asked him if I buy a Taurus from this dealership, does that mean my wife is going to have a Plitt Taurus? The guy just looked at me in disbelief and said he has been selling them for years and nobody ever asked him that? 😜😂 4 Share this post Link to post Share on other sites
ebinmaine 79,964 #133 Posted yesterday at 12:09 AM This morning I spent a couple hours removing the entire computer wiring harness along with the vacuum lines. There were two wires in the whole kit n caboodle that need to stay. Both for sensors/ sending units. One is the oil pressure. The other.... I don't know. It's screwed in to the back of the cylinder head on the passenger side. I also separated the wires coming from the fuse box, ignition switch and dashboard areas. They're marked (what I know) below. Fuse box pic for my own reference. Here's the new and improved cleaner look. 1 Share this post Link to post Share on other sites
ebinmaine 79,964 #134 Posted 6 hours ago Today I got the exhaust cut & removed from just downstream of the catalytic converters. Those will be removed later. The muffler had an interesting surprise. Upon tilting it to remove it from the truck.. I heard rattling rolling noises. There was at least a dozen and a half acorns in the part of the muffler furthest from the open end. I was unaware that was possible given that this is a stock closed type muffler. Maybe it's in the design. Maybe it's got internal holes it wasn't built with. Doesn't matter because I never intended to leave it on. I also got the unused canister vent and air intake pieces removed from under the hood. Also detached the fuel tank side of the unused vent hose. That'll be rerouted and filtered somehow when the bed is built. When the PO assembled the truck, this intake manifold port was hose attached directly to an upper vacuum port of the carburetor. One vacuum source attached by hose to another vacuum source. It was also thoroughly gunkified with the orange sealant you can see. I have no idea what purpose that would serve. In other news. This is Seamus. He VERY rarely makes appearances while human people are in his barn. Today I lucked out and got a pic. 2 Share this post Link to post Share on other sites

I found online that there are some Ford inline sixes that used that intake port to get a multiple vacuum tree port. I still don't see the usage of a direct vac to vac connection.
