96 Imp SS Lt1 into 97 s10 ?

[Twiz]

I've read the sticky and know what mounts I need to use and pretty sure on the headers. What has me so far is the wiring. I have a complete wrecked 96 imp ss that I can get parts from. The car is ofcourse an auto but the truck is a 2.2 with 5 speed

[Twiz]

bump because I'm still needing info so I can get started.

[Twiz]

Bump....Nobody has any answers ?

I can't answer about your computer questions, because your truck is a
newer model than mine.
I am having a '95 LT1 froma TransAm installed into my '94 Sonoma.
We have had all sorts of problems not mentioned in any of the threads
or the transplant books! The solution has been: more time & planning = $$$$!
On the wiring, we were told that the standard ECM was a plug and play.
Not true for my truck. I am having a custom harness made that melds the
two of them into one. The normal truck functions will be done by the S10
part and the new engine operation by the LT1 part.
I had an in-th-cab ECM. This is being changed to the location
probably on your truck, on top of the overflow bottle. But the mount that we
got from a '96 truck does not fit the LT1 computer! We will have to modify.

I insisted that everything that worked before had to continue to work,
ABS, p/s, A/C, windows and cruise. We'll see ....... not done yet!

you need to give jared at current performance a call he can answer you wiring questions. I'm pretty sure he can make to a custom harness to get rid of your headaches too. I got one from him work great and just plugged in wiring was no problem.

Yeah both the 97 s10 and the 96 IMP had the ecu's under the hood but the s10 on the pass side and the imp on the driver. It looks like all I need to wire up is the harness that comes inside the cab from the engine harness. I'm planning on after I get it installed and running right to move the ecu inside either under the dash or pass seat or even inside the console a friend of mine is starting on this week. I'm going to be using the imp's shifter too but with a shift boot on it so it looks like a 5 speed. I need to find out what the wires are for that run inside the cab and inside the car. I'm sure some of them are for stuff like starter signal, ac turn on, tach, speedo, charge gauge, oil pressure. I'm just not sure which ones are which yet.

well i really didnt combine the 2 harnesses to much but i did some mines a 96 s10 that originally had the 2.2 and a 5speed,, i stuck a 94 camaro z28 engine with a 92 camaro world class t5 behind it. i currently have it running im just doing the cleanup on it right now and get some kind of exhaust on it. i used the s10 computer to run the gauges and such. all u have to do is plug the pig tails for the s10 into the gauge sendors on the lt1 mine were all the same connectors,,, the oil pressor sensor, temp sendor, connect the alt wires from the s10 harness to the lt alternator and it will read the voltage on the gauge in the truck. on the 92 camaro tranny even my backup switch and speed sensor pluged in. im not sure if the speedo works yet but i'll find out tomarro. i know my tach is off bad thou,, dakota digital makes a thing to make it where ur stock tach will work with the v8 thou thats prolly where ima go.

For the tach to read right: http://www.s-series.org/htm/how2/recalibr.htm

I'm wanting to do this so that the truck can still pass obd2 state inspection and not throw any cel for anything. I might even run ac on it as well

hey good info!! i just got my inteior back together lol. i started it up today to back it out of my driveway for a around the block testdrive and found i couldnt get it into reverse,2nd,or 4th,, i set my engine so far back my shifter was against my bench seat and wouldnt go all the way into the back gears.. so i went and found some leather electric blazer seats for 40 bucks! in near perfect condition. the blazer i pulled em from hada sun roof i want. i found a supercharged 4.3 in the yard today as well. all in all i think today was a good j/y day...

oh yea where is that chipboard in the pics,, in the gauge cluster? how do u know what cap is c103 is it labeld on the board?

I havn't started on my swap yet so I havn't done the tach mod yet but I think it's in the cluster.

I'm waiting to get my mounts and headers delivered. I'm bagged in the front so I can't wait to see how much it slows down the up on the truck....lol

If I can get the info on the wiring so I can get it running and drivable asap, I'll start on it as soon as the mounts and headers get here.

[Twiz]

Nobody has any info on the wiring ?

[Twiz]

Mounts and headers are here so I need the wiring help asap.

[Jim_Rockford]

the wireing for the b body engines isn't that hard, but it is best to have a FSM for both vehicles so you know what wires are what going inside to the dash.

I have alldata but it doesn't show everything

in case it helps anyone, its the same formula as resistors in parallel. (1/C1)+(1/C2)+(1/C3)+...=(1/C_total)

Each year is going to be slightly different. I used Chiltons and Haynes manuals for both donor vehicle and the truck. I also found various diagrams off of the internet.

Definitly take the time to go over the schematics and do your due dilegence before ripping through wires.

Or like stated before, call current performence if your not up to tackle this task

That'd be too easy and less pride....lol I've been going over the diagrams from alldata the past few days when I've had a few spare minutes. I'm gonna make sure I have all teh wiring figured out on paper before I even pull the 2.2 out because I drive it daily. I have another ride but don't like driving it because it's a mini van and slower than the s10

Go ahead and yank that engine. You're gonna be working on this swap for longer than you're thinking.

I think that maybe some more specific questions would help. "Help with wiring" really doesn't help US help YOU...

Essentially you need to get your LT1 harness and find all your "loose ends" - I believe most are in the C210, C220 & C230 connectors. Those ends will probably end up connecting to your S10's connector that enters the cab at the brake booster area.

You'll want to figure out what wire from the LT1 harness mates to the wire on your truck. Make the connection. Then continue. Easy stuff, right???!!!

Yep easy stuff just need to find out which wire is which.

The best on-line source that I have found, with pictures and diagrams you
can understand is at:

There is a whole bumch of info there, and links for even more stuff!

I havent done an lt1 swap personaly but i can imagine the wiring involved. If you have some good wiring experience id say do it, it wont be that hard as a lot of obd 2 cars use similar i/o for sensors and what not. So wiring your truck to work on the lt1 computer wont be hard. Its a matter of power, grounds and a few others like fuel relays fueses data line tach a/c and what not. Make sure you have good diagrams for both vehicles. Some people will tell you you need both the origional truck computer and the lt1 computer. This isnt true. The origional trucks computer is used for controlling ABS on SOME truck models, this can be solved by getting a stand alone abs module from an eirler truck. Or getting rid of it like i did. Your guages will work once you get the sensors like temp and oil sender setup correctly, the guages feed off them. Fuel and battery are ran through the body. Tach runs off the coil and will need recalibrated by riping out the guage cluster. And speedo will work with the usual vss gm sensors, uses the one off the trany. Hope this helps.
