410 fortune - 5.0L EFI 4R70W drivertrain conversion

[Bird76Mojo]

With this sweet rig, you seem the the guy to ask about my problem. Swapped a 92 T-Bird 5.0 in to my 87 Ranger. Much the same harness as your BII..

The only factory gauge I can't get to work is the ammeter. Nothing I've tried will make it show that it's charging. It does show when it's discharging, like when the headlights are on, etc, so I know the gauge still works. I just don't know how to wire the alternator to the factory 87 Ranger harness to have it show charge status. I think I'm missing the factory shunt?

I used a Ron Francis efi harness and left the Ranger body harness intact, but unplugged/ditched the underhood engine harness, etc. If that matters..

Any tips for me? I've read the EVTM manual for the 87 until I was blue in the face. Even gave myself CO poisoning trying to keep warm in a shop for several hours trying to figure this one out, which made me even more stupid in the long run. lol

Sorry to clutter up your thread.

Nevermind. I've given up on the factory ammeter and I'm sending it out to Rocketman to be converted to a voltmeter.

Dang sorry I missed this

An ammeter requires a shunt for sure, I know this because my diesel generator uses an ammeter, shunt and circuit breaker in the charging circuit...which was giving me fitts
Ammeter will not read or work properly without the shunt in the system

I too would have gutted that gauge and converted it to a real voltmeter

I was really happy to work with the 5.0L harness however, it is a stand alone drivetrain harness, which is nice for a change. the stupid 4.0L OHV harness has the headlights, ABS, power distribution, and a bunch of other junk wrapped up with it. The 5.0L goes from computer to engine and trans, and from computer to truck, tweo big plugs, much much easier.

I am loving this OBD-II system and cannot WAIT to get a laptop interface and tuner.

Yes, I realize I'm quoting a post from 2005. Any idea if the '96/7 4.0 OHV drivetrain harness is also stand-alone like the 5.0? I would assume the Ranger is the same. And with the Ranger it would seem you get to choose a harness/PCM from 1995 - 1998, as the Ranger got EEC-V a year earlier and didn't get PATS until 1999.

Did you ever get a tuner solution of some sort? I'd just be looking for something simple and reasonable - more to take certain functions out than anything.

Currently I still have a MIL
the codes are canister vent valve circuit incomplete, fuel tank pressure sensor, and fuel tank level circuit.
This is fantastic news because those are the 3 wires that have not been hooked up yet This week I am dropping the tank on my 96 Explorer donor truck and removing the necessary sensors and wiring from it. I am headed to the junk yard to purchase a complete 88 BII tank to modify. I have to cut some holes in the top of the tank for the pressure sensor.
once these sensors are intalled and wired in I expect the MIL to go away, I will then be able to pass emissions, which is good because my tags expired 05/05

One more for tonight. Since my car is historical, all it needs is an annual safety inspection. It doesn't even have a MIL any way! What if I don't have any of these sensors installed? Does it effect running in any way?

The 96+ 4.0 harness is similar yes

The big difference with the earlier trucks is they had the headlights and ignition module all part of the engine bay harness

In 95 everything went to the big 42 pin connector c110, c112, 115 depending on model and year, with this plug basically all drivetrain wires that connect to the truck run through here, except for charging, starting and ac… everything else is in there. So yes 95-01(02-04 sport and trax) all similar stand alone drivetrain wiring so to speak

Rangers did not have pats until 99/2000 that is correct

Forscan and a laptop is quite capable these days it can do lots with pats and such
Pats in 98/99 not that huge of a deal because it only disables the starter via the starter relay… easily bypassed. The 01+
Version of pats was harder because they disabled the injectors

Lasota and a few
Others can help you with tuning outside of what forscan is capable of

Without egr and some emissions sensors the engine bay or may not be happy… it is best to either tune them out or try to fool the pcm to think they exist. A tune can do a lot these days, our pcms are old enough to have been hacked by now… tuning is not as expensive or hard to obtain anymore thank goodness
