Explorer OBD2 Harness Re-work

[EFI Guy]

Sorry guys, I haven't been logging in much except to check private messages. I have added 2 new videos and a small update to the first post.

I will probably get around to making a part 2.5 later to answer any questions and show some more tips on wrapping and installing.

Hi Garry,
As always, thanks for the updates. I plan on starting my firewall harness re-work when I get back in town this weekend.

Thanks for giving us your time and sharing your knowledge!

Hey Garry, I followed the videos and everything works and is hooked up (well mostly, left a few like overdrive and high idle unhooked for now). However, the truck will start in any gear i.e. it looks like the neutral safety switch isn't working. Don't know if this matters but I hooked the reverse lights to the black with pink wire and the pink wire to the s post of the start solenoid. I guess I need to know the routing of power through the neutral safety switch so I can make it work and figure which wire I have in the wrong place. Any ideas?

Does this help. Keep in mind these are for a 98.

Glad you brought this thread back up. Don't know how I missed it originally!
It's great that you posted videos Garry. About the only thing we like better than pics of our Broncos and wiring diagrams, is videos!

I'll add my thanks and best wishes as well.
Maybe someday we'll get the chance to work together on some projects.

Best of luck and best regards,

PaulB

Chuzie, thanks for posting. Those are pretty much the same colors as my 2000 Explorer transmission. The diagram set me straight, I then called EFI Guy to confirm. Took me about 10 minutes to fix it.

Thanks for the kind words guys.
I updated the second post to add some trans tech for those of you using a different year trans.

I watched the videos a couple times and think I will attempt this myself. Thanks Gary, I just have one question about the resistor, How is it handled?

You want to put it in place of the 2 pin EVR connector. Brown/pink on one side of the resistor, red on the other. That only applies if your PCM code starts with SLL_ or is JFX0.

Thanks again, I'll be sending you my email address to get the comp flashed, it is a SLL3.

How the hell did I miss this thread? Glad I stumbled across it before I got fully involved in my project.

BUMP!

I just finished up using this information to put an explorer engine in my sons 1985 toyota pickup. Thanks Gary.:-*

Hey Garry,

Could you post some pics of where you installed you relay box? Preferably a 96 relay box and your fuse box supplying it?

Thanks!

First start of my EFI explorer in the chassis. I posted this over in my other thread, but why not here too. Thanks Garry for all your help.

Relay boxes... You mean like this?

Thanks!

Ideally with the 96 relay box you would mount it against the fender, right about where Doug has his A/C accumulator in the picture above (Nice work Doug!). Then the fusebox mounts on the slanted portion of the inner fender right next to the starter solenoid.

Pretty much anywhere near the starter solenoid will work for either. I do it that way to minimize the amount of wiring to get power to the fuse box, you can just pull it from the battery side of the solenoid. I also like to bring the start signal wire for the solenoid out there too if it's running a 4r70w.

Ok, I got pinged to answer some questions on my build regarding air box locations.

I have pictures of my 68 and 71 builds with a plastic divider in place to prevent fan wash and try to keep fresh cool air for the engine.

The second set of pictures I download from this site. (I do not remember who) I like the custom work, but I lacked the skills to make it myself. And I did not want to mod the bronco fenders that much...

And if you want to run an Explorer fuel pump assembly in your Aero tank, this is what it looks like. You ask Aero to build it this way... You send them the Exp fuel pump assembly prior to them building it...

I have a 2001 motor in my 71 and it cleans up the fuel lines by not having to run an external regulator and return line by having the factory assembly which has the regulator in it.

Some stay away from the latter Exp motors with no return line, higher fuel pressures (60psi), smaller injectors (17lbs vs. 19lbs). The pressure regulation is done in the tank and the higher psi makes a 17lbs injector perform like a 19lbs.
