Taking the 302 plunge, any help appreciated!

i believe the harwood book (i never read it) mentions that using a 1989 f-150 5.0l ecm will allow you to use your 2.9l wiring harness (hard to believe but they have the same pinout) and plug into the f-150 ecm. utilizing all of the same sensors and since both engines are bank-fired all that needs to be done is an extra inlector plug spliced in to each side of the existing 2.9 injector harness. several months ago when i was service manager of a dealership a user here contacted me so i could send him wiring diagrams supporting this claim. after i did so he ended up doing the swap, he told me that it really was that simple for the most part

i'll go back through my email (if it goes back that far) and see if i can find his username or his email

I can't very that info is in the Harwood manual. I have one for 1993 , which i know is similar to 1989-1994 wiring, and it still only deals with a '93 Mustang style harness. Also have a Harwood for 1997 Ranger, same info.
I've read about the wiring you mention here on TRS, but I can't say I would ever consider it for a performance swap. But it sure sound straightforward.

Is there a specific reason you wouldn't consider it?

That sounds like it would definitely simplify things (provided I can find such a specific part)....

Clicky!

Thanks for the swap link, it isn't an exact match but everything helps....I bookmark it all!

my guess is that the system in question is a batch-fire,where the more performance oriented systems are sequential.

that would also be a map system rather than a maf.

Gotcha, thanks for reply. I think I would rather just muddle through the wiring difficulties then.

they aren't real difficult...especially is you go with the 5.0 h.o. system;there's tons of info on this one.

The key to doing an Explorer (wiring) swap in an early (pre-'95) truck is to compare wiring diagrams. (an engine is an engine is an engine, so the wiring is the main difference)

For example, with respect to your '88, I would recommend the Harwood manual for that year. Harwood deals exclusively with the 1993 Mustang/ FordMotorsport harness.
Simply view the available Mustang diagrams to see what circuits you are dealing with, then find the comparable circuits in your Explorer EVTM. Not too difficult. The only part that would be odd is wiring up the OBDII port, if you choose. But the Ex EVTM will show what circuits this plug contains, and you could simply add this port in the engine bay. Totally un-necessary, but totally simple at the same time.

And if you use the Ex ECU/computer, you could certainly use that computer controlled transmission.

I am pretty sure I have sourced a good 98 Explorer engine and trans but it is missing the ECU. My head is swimming a little but I wanted to make sure that I would definitely need to source an Explorer ECU correct?

Should be easy to find. ECUs are in the $100 range.

A guess says the ones with a fuel return line will work, '96-'98, based on the chart here:

I have a good one from a 96, I will take 100.00 for it

After looking at the link your provided, it looks as though I will need the Explorer steering column as well because of the PATS? Also, would getting an ECU from a 96 pose an issue because of the PATS as well?

I might be interested in that ECU, depending on whether it is compatible with the 98 engine because of the PATS starting in 98 Explorers.

 

[Teddyzee]

I believe PATS can b removed from the ECU via tuning.
I have recently seen an Explorer ECU of unknown (to me) year for sale on the classifieds here or RPS, that had the PATS disabled already.

fawk pats.....always remove the pats. you can send it out and have it done if your remotely located. best thing you can do for yourself.

the last 5 years have really come far with home tuning, and the obd 2 systems at this point are the best bet imo. the newer the setup the better for the most part. moates and tweecer type setups will be worth it once you have invested the time to learn them.

 

[mike732]

Mine has no pats, as it didn't start till 98

google moates.
....most any dyno tuner.
