300 SWAP Wiring

So I bought a very beat up 70 a few years ago. The old 302 was blown up. I looked around for a deal on a fuel injected 302 and couldn't come by one. I however did come by a wrecked 98 f-150 with an inline six only 80,000 miles on it. So I got it for a song and a dance, made up some motor mounts put the beast in with a bodylift and a little firewall mods. Now the wiring.....I have the ECM out of the truck and all of the wiring harness for the engine compartment. My bronco body has a painless kit in it that went to the old carbureted 302. Now the fun part..What do I do try to mate up the six with the old harness or try a find a new one. Any suggestions?

Well I have a few issues. You call it a '98 with a 300 I6. That beast was never built. The last 300 was the old body style that was out of production before '98. Once we know what you really have then we can help dial in what you need.

I'd say your going to have to use the old harness as no new ones are availible for that swap. Your going to have to find out what wires do what and delete anything you dont need. I'm sure someone may have the pin outs for that computer might try the big bronco site. Good luck with that swap better you than me.;D

Well yeah you are right. I have a fuelinjected inline six out of a 98 f-150 i do not know how many cubic inches it displaces

No I-6 available in 1998. 1997 and newer has V6

Yep, that is why I am confused.

You are claiming something that was never made. So guessing on what you have is pointless. We need more (correct) information about what you have before we can go any further

Bronc, welcome to the site. If you have any pics of your conversion or a description of the fabrication it would be great. I picked up a '92 300 I6 the other day to put in my frankenbronco some day so I'm very interested in this. Keep us posted. Thanks.

Wow! Only his second post after just joining. Can you say "welcome"? We all had to learn in the beginning.

?:? He is not being ripped on or being given a hard time. People are simply pointing out that what he is describing is not possible. They are asking for more information so they can help him out.

Could it have been a Canadian or Mexican built truck and still have an inline?
Could it have been a mis marked or identified F250/350 with the old body style still?
If I remember, the old style only ran one more year (to '97) in the HD trucks, but maybe there were some old-body style '98's too? Like a Crew-Cab F350 or something leftover like that. Don't know if the big trucks got the six at that point or not, but wondering at least.
Of course, according to the chart Viperwolf linked to, there is only info up to '95 anyway, so maybe none of that is even remotely possible. But hey, it's Ford we're talking about!

Not a rant and no response is needed.

Well it isn't pleasant for a new guy. When I think "guru" as in Bronco guru, I think of someone who is knowledgable, and willing to teach, coach, and develop those who are not and want to learn. I am sure that some of you have forgotten more than I'll ever know, but I'm OK with that as it allows me to spend more time with my Bronco to figure it out myself. As the title says, this is not a rant. I don't want a fight, just an understanding that some of us are still learning what you take for granted.

My guess is that the 5 in 1995 looked like an 8. Or, the seller didn't really know. Hard to say. If we can get a picture, it may help identify it. I'm betting that one of the pin outs Viperwolf posted a link to will work. Is it Speed Density or Mass Air? Did you get the engine harness and ECU with the engine?

It must have been manufactured in the twilight zone. The truck I pulled this I-6 out of had a factory decal on the door frame that said 98/ but hey it was in a junkyard for a few years maybe it was dirty or I didn't have my glasses on when I read it. Any ways no that multiple people have had their chance to prove they know what specific year that FORD offered the inline six in their vehicles. Back the the question at hand. Wiring? And thank you to those of you who actually had helpful advice about the wiring

Yeah I pulled the engine wiring harness and the ECU. I will go locate the numbers on the block to correctly assess what year it is

I really want to see how this works out. Fun to see more stuff on the I6. Remember Hot Rod magazine and Dare to Be Different?
