All,
I am going to try and compile a list of these FAQ's... Please if you have a link and question that is always thrown around... please post so I can put this together...
1. What Headers will fit a Stock K-member?
2. What Headers will fit a Tubular K-member?
3. Can I use a 1996-1998 GT Wiring Harness for a 4V engine?
(Can I use my GT computer and harness to start the car as of right now, (aside from the IMRCs, and PATS which are wired open and disabled) the car should fire and run off of the gt programming until i can get it to my local tuner to accomidate for the 24LB injectors and so forth?)
4. '88 dash to the Modular wiring.
Thanks

1. What Headers will fit a Stock K-member?
We have had many use the JBA mid-length headers with 3" collector with many aftermarket K-members and even stock. We also have our JBA shorties and they will work 100% but they have a 2.25" collector so you have a smaller outlet on the headers. Check out the mid-length images below and if you need any additional information please let me know.

CCRM QuestionThe bulk of this era ECU are of the CDAN4 family. They are all literally the same physical EEC, but with different calibrations in them.
So, to answer your questions more directly: The GT ECU will work great, the fuel trims will be quite a ways out to start, but it will run and drive. If you want to, you can add in the wiring for the IMRC's to the GT harness. It's up to you. The GT EEC definitely has the abitlity to control IMRC's. Your tuner may modify the GT calibration or use one of the cobra calibrations or a combination of both. Do you know if he will be chipping the ecu or using a flash programer?
Mod fox's car is pretty much identical to your setup. Lincoln motor with IMRC wired open and a GT harness and ecu. In his case I simply modified the GT calibration.
4. '88 dash to the Modular wiring.
'88 GT ready for wiringFuturaGuy said:Connectors C213, C216, and C259 all connect to their counterparts on the Modular computer harness. The Modular harness also has a fourth connector, C202, which is a round white connector with provision for 4 pins. In non-California cars, there is only one pin, circuit 29, a yellow and white wire that connects to the gas gauge. Not having the mate to C202, I ran the yellow and white wire to a vacant hole in C216.
On the other end of the harness, I used an 11-pin connector (with 5 blanks) that I labelled C1108. The two halves of the connector came from the damaged harnesses from the donor car, and was the connector (C108) behind the right head light that connects the computer harness and the fuse box harness. The eleven wires shown connected thru C1108, with one exception, come from the bundle in the '88 dash that used to go thru the firewall next to the steering column. C135 mates to the green 8-pin connector from the dash and goes behind the passenger kick panel to feed the old computer. C245 goes to another small jumper harness that connects to C243 and C244 in the dash. Those normally connect to a module used only on the 5.0 GT's, otherwise they dead-end. C232 is the port for the OBD-II diagnostics. Since I'm re-wiring the entire car, I put that connector in the center console where it's easy to reach.
It made a very neat installation (some people on this board seeing the photo of the harness said it looked OEM - I'll take that as a compliment) and the underhood wiring is completely stock. The local Ford dealer actually has done some work on my car since the Mod Motor was installed and they had no trouble with it. It was just like working on a Mustang.
Thanks
