Formatting and merging, etc.

K, here is my notes, LMK if ya need help

Move Pin #4 on the Blue Connector (Black/orange or pink)
to Pin #4 on the Red Connector (Just cut the old orange/green wire it's useless on the T2 Swap part)

Move Pin #14 on the blue connector (white/orange)
to Pin #14 on the Red Connector

Map Wiring
Use the White/Violet one off the "underhood map" or the Red Wire on the stock map too The Red connector Pin #1

Use the Dark Green/Red off the "underhood map" or the Black wire on the stock map too The blue connector Pin #19

Use THe Black/Light blue wire off the "underhood map" or the white wire on the stock map and splice it into The Red Connector
Pin #25

For the TPS, just match the wires on the old connector too the new connector

For the AIS, match up the old wires too there matching ones, and for the two extra ones

Black/Yellow To Pin #16 on the Red Connector
Violet/Brown to Pin #20 on the Red Connector

This is a picture of the "Pinouts"

Just incase you get confused check those pages this is all the help I had too figure it out, you should do just fine, took me like 10 minutes after getting the wires through the firewall... which too me about an hour

Re: 85/86/87 T1 To 87 T2 Wiring *MAKE STICKY*

Bzzzzzt. Minor error here. Should be "move pin #14 on the blue connector (white/orange) to pin #9 on the red connector."

On the map sensor ? Do you need to rewire in on all models or is this year specific? I am doing my GLH today, Im about finished with the wiring except for the map.

Someone please help me to understand this Map wiring better. Isnt the map on the Logic module?

The only wires you need to add are the additional wires for the ais. Your 86 LM is the same as a glhs.

The wiring they are talking about isgoing from 86 based (GLH/GLHS) and earlier cars to 87 Shelby Z TII based (underhood map)

I found this page very helpful.

http://fwdmopar.50megs.com/T2conv.html

I suggest reading several times to fully comprehend.

Also check Gary's and minimopars sites as suggested in previous replys.

I finished my conversion last summer and didn't have a single wiring error. I went from 86 daytona t1 to 87 daytona t2 so I ended up moving wires. I also pulled wires out of the t2 harness becuase I wanted a clean look and didn't want to splice wires. Picky me.

Remember to take your time and read/ask if you are confused or uncertain about anything. I also got pinout information of the 86 t1 and 87 t2 LMs and went pin by pin to find the differences. This made it easier for me to understand what the articles mentioned above were talking about and what I needed to do.

Hope this helps.

Try this.

The first link is your current 86 LM pinout and the second link is the LM pinout you need your wiring adapted to for the T2 conversion.

link 1: http://minimopar.knizefamily.net/ecu/lm-1986-t1.html
link 2: http://minimopar.knizefamily.net/ecu/lm-1987-t2.html

What I did was printed them both out and found the differences between the two and made the appropiate changes. Pay close attention to wire gage and color and also your grounds. Also I think my wires were a little different when it came to the EGR solenoid because the T2 daytona didn't have it so they used that wire for the purge canister or something like that. I think it talks about it on the links above. When I was all done, I went through my LM setup and check it pin by pin with the pinout from link 2.

I went from an 86 daytona T1 to a 87 daytona T2 LM and worked for me. I didn't have a single wiring issue and car fired right up. Just take your time and double check.

Hope this helps.

I'm going to print the pinouts for 86 T1, 86/7 GLHS, and 87 T2.

My question is - will I have to relocate any pins if I run a GLHS computer in my 1985 T2 Conversion L-body. Do I simply just have to add the 2 wires for the AIS - nothing more?

You just add the wires... Did it to my 87 SC

Ken,
Does this mean that a MP logic module for a T1 86 SC would be the same as a GLHS computer? I could switch to a blow through setup and only add the 2 AIS wires to the computer and run the T1 MP logic module without an intercooler for a little while while I gather the Intercooler parts?

I am just trying to make sure I understand the differences between T1 and GLHS. Any info appreciated.

Pat, yes.. like TMEF said.. My duaghters car is set-up but not intercooled (don't want to give her the ponies)

No... Just read this closer... the actual logic in the cals is different. GLHS cals and SC cals share the same pinouts and wiring, that is all.

Regarding the Air Charge Temp Sensor - will the plug on my 85 Log Intake harness plug into the T2 style sensor? I'm sure I have to re-pin it, but I'm just wondering if the plug itself fits. And just a FYI - according to those charts on minimopar - 86 T1, 86/7 GLHS, and 87 TII, all have the Air Charge Temp on the same pinout on the Logic Module.

Ken,
The logic is only different because of the T1 vs. T2 is that correct? The actual operation of the AIS motor and TPS is the same isn't it? I guess what I am trying to say is: If I am wired for the newer AIS I can run the T1 cal with a blow through setup and only add two wires. The actual operation of the logic module will allow this?

the plug and sensor are the same

Unfortunately, that's beyond what I've tried.. I had GLHS modules lying around so I swapped them in.

No Idea if the 86 T1 module will work with the new set-up. I do know the 86 modules are pinned to handle it... Not sure if the logic is there though.

85/86/87 t1 to T II wiring

The 85 and 86 LM are different and are not interchagable. You can swap a 85 LM into an 86 and it will run in limp mode. The sync pick up is different necessitating a few addtional wire swaps in the connectors.

The 86 and 87 LM are essentially interchangeable but the 87 LM has more memory and adapts the boost ramp up better than the 86. The 86 has 2 memory cells and the 87 has I think 5. Anyway the EEPROM in the 85 and 86 are 2764 and the 87 is 27128.

You need to change the distributer and HEP to an 86/7 model and it (the 85) will work fine.
