5.0 explorer. Distributorless?...

[cscotted]

Man i wish i could figure out how to post pictures. This mess of wires is hilarious......

I went ahead and killed the following pins in addition to the others

Pin#2. MIL
3 TR1
49 TR2a
50 TR4a
56 vapor valve
64 Tr3a
67 can vent sol
69 ac relay
81 CPC sol



Crossing my fingers......

 

[cscotted]

Ok. So i have the engine installed and no issues there,

Fuel tank modification to accept the explorer pump

 

[cscotted]

And now the super fun part. Wiring

 

[cscotted]

Added a set of BCB ceramic headers on the GT40p heads close fit and a 90 deg boot will be needed on #4 but other than that i like them

Progress looks good.

For your o2's keep the htr control for the 2 upstream sensors, you can ditch the 2 that are downstream.

IIRC they are all spliced together form the factory for the heater circuit and signal return. Find the splice and cut it neatly, then add marine heat shrink over it.

The only other thing you removed that I would keep is the MIL.

Looking good.

 

[cscotted]

Yeah, after i originally posted the things i removed, i had to go back and re pin a few things.

Here is an updated list of what i kept from the PCM

FUEL LEVEL IN. ( not sure if needed but i kept it)

FUEL PUMP MONITOR also not sure but kept

PWR GROUND
IGN COIL2
KAPWR
VSS
HEATED O2 #1
PRESSURE TRANSDUCER
VPWR
FUEL INJECT. 763 and 1

IGN COIL 3
FUEL PUMP CONTROL. Kept this for factory exp pump
IAC SOLENOID
CAM POS IN
HEATED o2 #2

HEATED O2 #1 pwr
Heated o2 #2 pwr

FUEL INJ 864 and 2
PWR GROUND
IGN COIL4

 

[EFI Guy]

You can ditch the fuel level in, but keep the FP monitor.

Pressure transducer? What pin # ?

 

[cscotted]

Pin 62. Its part of the explorer fuel tank with the built in pressure regulator. Due to the single fuel rail on the explorer

 

[EFI Guy]

That's not a fuel pressure sensor, thats a fuel Tank pressure sensor. The PCM uses it to test for EVAP leaks.

 

[cscotted]

Ah nice. Ok. I kept it thinking i needed it. Now i know.. Thanks man..

 

[cscotted]

I sent you an e mail also. When you get a chance. For PCM. numbers EQE3

 

[cscotted]

Really like the clean install of the explorer components. But am battling with options now...

 

[EFI Guy]

Replied.

That looks nice!

 

[garberz]

I'm starting this very soon. I'll have some questions for sure. You being several weeks ahead will be a big help.

Im doing mine a little bit different than previously thought out, however im still on track and feeling comfortable with what i have going.. Today after work i got the starting relay labeled and ready, the Pcm relay and the fuel pump relay ( triggered by ground from PCM relay)


Need to work on a few more wires but im feeling good about it...no pictures today. It would be kind of boring

 

[garberz]

...I'm doing mine a little bit different than previously thought out.

What are you changing from the original plan?

 

[cscotted]

I was going to use the explorer central junction box ( dash fuse panel) but decided not too after talking with one of the only two people who have succesfully done this.

 

[cscotted]

I only need 3 additional fuses. So it seems senseless to use a 36 slot fuse panel for that. I have all weekend to think about it since i have to go out of town

 

[EFI Guy]

If you want to get technical, you should have 5 fuses total to run the system. I see no problem with connecting KAM to the EEC relay fuse though. That would get you down to 4.

 

[cscotted]

Well. I meant 3 additional minus the fuses in the battery junction box
