ghcoe Posted November 10 Author Share Posted November 10 A update for this weekend's adventures in F/I. Friday after work I stopped in at the local junkyard and picked up a few more parts I needed. I really only needed a couple of plug connectors to solder into the harness, but wound up with a couple of other items. As per usual when I go to the salvage yard. I destroyed a couple of plugs trying to disassemble them to solder wires to the pins. I gave up on that and decided to just solder the plug wires into the harness. Not as clean, but not as much as a headache to do. The throttle body that I had found, to try and make this project work, was off of a 1994 Ford Escort 1.9. When I was assembling the wiring harness I had thought that it would have been nice to have the plug for the Idle Air Control valve (IAC) come in from the same side that the Throttle Position Sensor plug did. It would look cleaner and would save from kinking the wire to make the bend into the plug from the opposite side. I happened to look under the hood of a 1993 Ford Escort and found this. The one on the left is off of the 1993 Escort. The one on the right is off of a 1994 Escort. Not sure why they would have changed them for 1994 up, but they did. Makes the wiring longer for those years, but works for my project. 3 Quote Link to comment Share on other sites More sharing options...
ghcoe Posted November 10 Author Share Posted November 10 Next. I was also trying to figure out how to get a air filter on the throttle body. I had a few plans, but while looking at the Escort air intake I noticed that the rubber hose made a nice 90 degree bend, similar to what I needed, and it already was the right size for the throttle body. I cut the intake hose with my radial arm saw where I thought it would work. And the test fit. After the cut the opening turned out to be about 60mm. I found a 63.5mm air filter on Amazon for $15.99. Then I need a way to connect the two. So, I looked around and found that 2" PVC pipe is 60.325, this should work as my connector and provide a place for me to install the Intake Air Temp sensor (IAT). The air filter is not here yet so I will have to update the results at a later date. 1 Quote Link to comment Share on other sites More sharing options...
ghcoe Posted November 10 Author Share Posted November 10 Yesterday, I did a final run of the wiring harness before starting to solder on pigtails and install new plug ends that I have. So, the wiring harness, as a recap, is a mixture of new wire soldered to old pins. Plug and pig tails soldered into harness. And, new plug ends attached to new wire. After a few hours I it came to this. In the above picture is the harness ready for install. I have three engine bay runs now. Top one is the fuel injector run. Middle is the power supply and Fuel pump relay. Bottom one is sensor run. Coiled in bottom right is wires not used and interior ran wires. I will be working on the fuse/relay box a bit today. 3 Quote Link to comment Share on other sites More sharing options...
ghcoe Posted Sunday at 23:57 Author Share Posted Sunday at 23:57 This weekend was more wiring work. I verified and rerified the wiring to make sure all looked right. Once I felt comfortable with that I started to wrap the wiring up with Wire Loom Harness Tape. $5.99 for two rolls. Turns out one roll was enough for this project. The tape goes on nicely and makes the wires tidy. After installation the wiring in the vehicle I will be adding a plastic wire wrap as well. Picked them up at Harbor Freight, about $4.00 per size. I also had to order in a oxygen sensor bung so I can get a O2 sensor installed. I found this one on Amazon for $32.99. 2 Quote Link to comment Share on other sites More sharing options...
ghcoe Posted Monday at 01:05 Author Share Posted Monday at 01:05 I also finally got the relays wired in the relay/fuse box. Took me a few times to get it right, but finally I got it done. I then found a spot for it under the hood. I used self-tapper screws to attach it to the fire wall. I added plugs to the wiring to make the install go better and for future mods that I may have to do. This build right now is just for fuel only. Later I may go to timing control. I figure one thing at a time right now. I also made a fitting for the air cleaner to intake hose. 2" PVC pipe works great. I drilled a hole in the PVC pipe to accommodate the GM type Intake Air Temp (IAT) grommet. Looks pretty good, I think. Well, that is about all for this week. Hopefully I will get the wiring in next weekend if the weather holds up. 1 Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted Monday at 09:06 Share Posted Monday at 09:06 Nice progress. Big fan (convert) of the PDU's to do away with the requirement for fuses/relays now Quote Link to comment Share on other sites More sharing options...
