85lebaront2 Posted December 11, 2017 Share Posted December 11, 2017 Thanks, 85lebaront2! I have removed the plenum before, in fact, the entire engine. I have the Torx socket along with a socket extension that makes the screw removal a breeze. Presently, I've got an oil leak that is severe, meaning that oil is leaking either from the rear main and/or the oil pan and possibly the valve covers. It's so bad that it smokes in the engine compartment when the oil hits the headers. So, I'll be removing the engine again, much to my shagrin. However, removal may present an opportunity to streamline things a bit with regard to the harness. I'll also replace all hoses and vacuum lines. Unfortunately, vacuum lines from Advance auto and other such places are crappy and degrade rather quickly. Any recommendations on a place to buy GOOD vacuum lines are welcome. I am considering sending the throttle body out for a go over. The place I have in mind resets the throttle screw to its factory settings. The TPS is a Motorcraft and fairly new as is the IAC. So I should be ok there. I understand the difficulties with the TPS, but am hopeful a factory adjustment is all that I will need. I do have some new injector connectors if I need them, but am interested in other connectors you may have that will function well. I am also interested in fuel line recommendations. The original fuel lines are heat treated onto the fuel rail and a pain in the rear to remove. I previously removed those and replaced them with standard fuel lines from Advanced Auto. No too certain I like those except I have no apparent fuel leaks. I've never tested the fuel pressure. The fuel pressure regulator is relatively new and a Motorcraft. Possibly, there are other configurations I can use to update the fuel rail and if anyone knows of any, I am open to suggestions. I appreciate the power of this forum and the assistance both in knowledge and in materials. It was not expected, but certainly appreciated and an overwhelming surprise! Steven, let me look at the hoses I bought for my LeBaron turbo fuel system, it runs 55 psi at no vacuum and rises to 70 at 15 psi boost. I will get the information and the clamps I am using along with anything else. Hose is to SAE spec 30R9 and I ordered it from Amazon along with the full circle clamps (not worm clamps). These are the clamps I ordered: https://www.amazon.com/gp/product/B0040CU0HM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 And this is the hose: https://www.amazon.com/gp/product/B06Y2D4BQP/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1 The hose is showing as out of stock, but it may be back in later. A good parts store should carry it, it is expensive but well worth it. You also need to make sure this government mandated crap we have for gas won't degrade it. Fuel system, on the truck there is a reservoir on the frame behind the high pressure pump, in the 1985.5/1986 trucks it has a paper element fuel filter inside it, Fram makes a replacement so you might want to change that while you are doing all the other work. On the vacuum lines, if someone has an unmolested set for the engine and can carefully package them so they arrive undamaged might be the best bet. If you look in the "for sale" section, I have a set of the vacuum valves for the 1985.5-1986 5.0L EFI I had gotten for my son's 1986 F150 and we never needed them, one of the lines had cracked and I carefully put it together with a short piece of the correct color heat shrink tubing. It however stays stationary and doesn't move. AutoZone used to carry rolls of black hard plastic vacuum tubing. I have never messed with the end connections between my 460 fuel rails, never had a problem with them. Link to comment Share on other sites More sharing options...
NotEnoughTrucks Posted December 12, 2017 Share Posted December 12, 2017 Hi Ray - Thanks for the photo. It's a bit hard to see everything and I have a few questions about the harness. Does it have the following connectors: coil egr iac tps engine cooling temp sensor MAP TFI Ignition relay connectors Fuel pump relays oil pressure sensor connector Are the fuel injector connectors in good shape? Are there any broken connectors? Sorry for the questions and in no way do I want to appear ungrateful. However, if the harness doesn't match what I need it doesn't make sense to proceed. I do appreciate your efforts to help! Hi Steven, Sorry for the drop and run response here, but it's been a bit of a hectic week. Here are some more detailed pics of the harness. It should be an exact duplicate of what you have and you may see some minor damage and bundling issues. I could deal with this before I send it. I do have a few connectors on hand and I would clean it anyways before I send it. I will disconnect the ignition coil as it is bulky and heavy enough to add extra cost to the postage. You may also notice the fuel injector connectors are actually a separate harness. Possibly yours is still usable? This one is OK, but has some taping issues. I will pull the remainder of the harness out in the next few days. It becomes the dash wiring harness and splits to the L and R sides of the engine compartment. Again, some weathered connectors under the hood and some taping issues, but it does look to be in unmolested condition. Back to work now! Link to comment Share on other sites More sharing options...

Thanks for providing better photos. Do you think the connector is the same as mine - the number of pins, wires running to the correct spots to match my ECM, ect? It's my understanding that different ECM's have different pin placement. I'm interested in making this purchase, but just want to nail down some of the specifics. I'll also make one modification on it. I've moved my TFI module off of the distributor. I have the module mounted inside a heat sink which is then mounted near the driver side headlight. I'll swap that out and add extensions once I get it. I did so to remove the TFI module away from the excessive heat, thereby prolonging its life. Thanks!!

Like Bill says, only two different types of connectors and all the 85/86 trucks are EECIV, so 60 pin connector. The pinouts themselves will not vary within the 85/86 truck application, but there were differences in other models. SEFI vs. batch fire, electronic transmission control and MAF vs SD come to mind, but none of this would apply to an 85/86 EFI 5.0 truck. Of course, the EVTM is right here should you need to trace any pinouts. http://www.garysgaragemahal.com/1986-evtm.html Link to comment Share on other sites More sharing options...

Slane347 Posted March 23 Share Posted March 23 Gee, I wonder where that EVTM came from?? Some old man I know. Hey guys, I tried to start a new thread but it wouldn't allow me to. I have an 85 F150 4x4 5.0 EFI. I bought it and it had been sitting in a field for 7 years. Majority of the wiring under the dash is trash, due to rats, not sure that I can even see what goes where to splice wire into it. I got a wiring harness from an 86 f150 with carberated engine from a salvage. Would this be a direct replacement since mine is EFI and the salvaged truck was not?
