Does anyone have a wiring diagram to wire up a TII harness to the GSL-SE computer?

 

The GSL-SE computer is not capale of running the 13BT, so I cant see why you want to do that?

 

The N304 ecu doesn't fit the plugs in the TII harness... you could use the N304 ecu, but you'd need to get a boost sensor and tons of fabrication...

 

I have a harness and a computer for a hundred bucks if u want it give me a call (954)895-3928. We can meet half way if u want to p/u

 

You're in luck.

I've finished 99% of the wiring diagrams to go from 84 GSL-SE to an 88 TII. This involves part of the front harness, the EM harness, tranny harness, all sensors, coils, solenoids, ECU, etc on the TII. A total conversion that should be street/emissions legal. Spent alot of time doing this wiring setup (thinking time--not doing).

I'm far enough along to post the wiring changes--keep in mind I have not tested anything yet--but I've done alot of system wiring stuff on other types of equipment, so I feel pretty good about it. Anyway, use at your own risk.

Most likely there are things you will want to do that are different and you'll have to work that out--though I'll be glad to offer advice.

I'm hoping to do my swap by the end of the year. Rotary Resurrection is currently rebuilding the engine.

I'll try and get something up this week, but I go out of town next week-- I will get something up soon.

Feel free to pm me.

p.s. yea what they said about the SE ECU is exactly correct, forget about it.

 

The ignition on all 1st gens are run by a distributer. All the triggering, etc. is done there. If you're trying to wire a TII to an -SE ECU, then you're nuts...

 

Guess you could run the mechanical dizzy, but there are many other reasons not to use the SE ECU:

1) it has no concept of boost and how to adjust fuel for it

2) the fuel/air map will be off, unless you use the SE AFM

3) it won't be able to adjust timing for knock (detonation)

4) can't even sense knocking--but then again many people don't care about that--but should

5) would have to use the SE injectors, what would you do about the other two (TII has four, SE has two)--unless you ran some sort of piggyback unit.

IMHO too many reasons not to use it.

If you can afford it and don't need emissions, get an aftermarket ECU.

Sweet man. I got about 90% done with doing that for a 89 N/A conversion, but I didnt want to release it, without my engine working perfectly first. My custom side of the harness works just fine, its the 18 year old stock other side that I eneded up having problems. I guess somewhere between is being ripped out of the original car, and be fited all ****-eyed into mine, wires cracked, shorted, compnenets decided to miss behave. Thats the reason why I went carb, its just cheaper.....

With that being said, I know your aware that the passanger side of the harness does not need to be modiefied, its the drivers side that rusn through the dash that you have to worry about. Its really not that hard, just remove every thing that doesnt have to do with the EGI circuit, wire up the second gen fuse box, and wire a trigger wire from the ignition switch to the main relay, and your set!

 

Hornbm,

Yea, I count about 14 wires on the drivers side and 1 on the passenger side + the EM harness which goes right to the engine/afm.

I think I had more, but I cant remember the number off of the top of my head. My setup was an S5 though, so the ECU had more pins, and double the clock speed. (A whoping 2 MHZ!)

 

Sorry guys, I misunderstood what my friend was telling me to ask.

He's using the TII computer from an 87 and needs to know how to wire the TII computer to the GSL-SE.

 

All I can really say is get a FSM for the -SE at least, and at least a hayes or chilton for the 87 TII. Go through all the wiring diagrams, mark the things that are the same, and different. Mark the parts that you will pull from the -SE and the ones that you need to add from the TII. It will eventually come together.

The wiring on our cars is actually really simple as far as automotive electrical goes.

 

FWIW--I have the images scanned, beware they turned out real big (size not bytes), suggest downloading them and viewing on your cpu. I'll work on downsizing them soon.

Here they are:

ECU Wiring #1
ECU Wiring #2
ECU Plug 1
FEM-02 Plug
FE-02 Plug
Fuel Pump Wiring

Your comments and suggestions are welcome.

Actually I'd do it the reverse way, get a haynes for the SE and the FSM for the TII. All you really need are the pinouts from the ECU of the SE, and thats in the Haynes manual. The FSM wiring diagrams for the TII are MUCH more complete than the haynes manual. Its what I did.

 

True, but there is more to the FSM than wiring diagrams. Even with the TII, most of the car is still an FB.

Here's a solution, save and get both

 

damn, those picture links dont work anymore, doesn any still have them???

 

Please repost this or mail them to me and I'll find some hosting. You could also use HTMLdoc to make a nice pdf out of it this time around

 

Yea, I had to remove them cause they took up all my space, and they were real big.

Will have the real ones up soon.

HALTECH!!!!

very easy hookup. plus you'll thank yourself later when you can do ANY modification and it doesnt **** up your drivability.

 

Perhaps, but some of us do like the OEM look and function.

 

Bumping this for the hosted pics!

My friend is doing a S4 TII with OEM harness and Rtek into a GSL-SE. Looking for as much infor as possible.

Thanks
