You can ditch it just make sure you run a wire to the choke that is not interupted by the pluggin for this sensor.

say u have an edelbrock carb with manual choke? do u still need to run that wire?


also, assuming u have the 2004r transmission.... where would the aftermarket lock-up pressure sensor mount? if anybody has any pics of it installed or can guide me that would be great

thanks

so both harnesses running to the computer can be removed? with the exception of the wires running to the transmission right?

You might as well remove the ones goign to the tranny too, they wont do anythingh without the computer. Make sure you get an aftermarket lock-up kit if yoiu have a 200-4r, I hear its bad for them to not lock up.

i cut out the two that went to the computer, but left the part going to the tranny, i put my lock up on a toggle switch by my shifter in the center console, i just left the plug in the tranny and grounded one of the wires, and then through power to one of them

if its got lock up, you need to wire that up or get a lock up kit, i also heard it wasnt good to do alot of driving with outit, i think it builds alot of heat maybee?

So in essence, once the proper carb/distributer/lock-up switch are all in (and pull the CES light) thats it? Do I really have to remove the wiring harness to the computer? It would be so much easier to just unhook the computer and leave the harness just in case the car would ever be convereted back to Computer controlled vehicle.

I think it was asked but didn't see a response... I see you need to wire a lockup switch for the 200-4R, but what about the TH350 in the 83-84 SS?

Could someone post a link to a kit they've used with this transmission?

Thanks!

Re-read the very first post. You absolutely - positively need a TV valve corrector adapter part when using an aftermarket carb (edlebrock/holley). Either 200r4/700r4 MUST have the proper TV cable geometry to work the shifts in the trannys. Bowtieoverdrives.com has a very good write up on how all this stuff works and what is needed to "get it right" IMHO! I have used their kits in both 200r4 and 700r4 trannys and they work flawlessly. http://www.tvmadeez.com/article/index.php

How is it that this post is still up? It has been here for like 5 months. Cut the engine harness, use a regular carb and distributor, run a switch to control the lock-up on the converter. Now wasn't that easy enough?

When removing the computer, there are two harnesses plugged into the computer. Do both of these harnesses get removed or just one of them. if just one which is it?

hello all, This has probably been answered before but Im going to ask it again. I just removed the computer and harness from my 85 ss. The harness was all one piece except for one connection that hooked up to the engine harness. What is this connection for? It plugs into the harness that goes to the ac compressor, HVAC blower unit etc.. I did not feel like taking the loom off the harness and tracing the wires down. I think if i remember correctly it was a two pin harness, with pretty thick guaged wire so i assume it was powering something up.

thanks matt

the harness u say i think is the one with the thick red wire? that's for the blower motor not needed if ur not keeping your a/c or defrost.

when removing the computer, it has 2 main harnesses, one of the harnesses splits into 2. all of it has to be disconnected. everything (gauges, lighting,etc) has it's own harness

no, i was wrong on the color. Here is a pic of the said connector. Im keeping all my hvac stuff. I hooked up the battery today and the blower came on, but the vent wouldnt move from defrost to the front vents. Im assuming that is probably ran by vaccuum? The car wont run so i cant check it now. here is the pic Its the little two prong connecter hanging by the manifold. It was connected to the computer harness and was the only thing connected to the engine harness. [img][/img]

and while im at it, what is this little booger right here? Its mounted on the passanger fenderwell (which is removed right now) right next to the electronic spark control module. Looks like a relay of some sort? Sorry about the questions.

if you remove the computer, does this allow the check engine light to come on and shut off when you initially start the car?

redbandit98, the top pic might be for the EGR sol or the blue plug on top of the carb(?) and it appears your EGR sol may not be present anymore(?). It should be mounted with the second to last bolt on the pass side back of intake.
The second pic is the ESC stuuf for the distributor. Not sure if you have vaccume advance now so it wouldn't be needed unless it is the newer style distributor that originally came on the car.

SO i see that you guys keep talking about the lock up with the 200/700r's now what about 350 trans? do i have to worry about a lock up with that? and how do you know if your even running a computer ? i bought my 87 ss with an goodrench 350 and edelbrock carb on it so does that mean the computers not hooked up?

Response to your second picture. You have two different items in that picture. The first item is the relay for your fast idle plunger on the carb. It extends the plunger out when the A/C is on to pick up the idle (blue wire can be seen in the pic). The second box is as you mentioned, part of the ESC Electronic Spark Control.

The plug in the first picture is either to one of your air injection system solenoids or it is the plug which actuates the mixture control solenoid in the carb. Wire color would tell you what it is. I believe the one for the carb has a blue and green wire in it. It would plug into the blue plug on top of the carb. My car is 15 miles away at my parents garage, along with my factory manual. Can't just run out to verify colors tonight. Can verify and repost.

Did some investigating today. The 2 prong plug shown in the first pic is part of the fast idle plunger wiring. It looks to be the plug that feeds the solenoid 12V and controls the solenoid via the computer grounding that wire. The pink/black stripe wire comes from the fuse box (IGN/ECM fuse 10 Amps) The black wire goes back to the computer for ground. The V6 and TBI Montes use this plug to control the fuel pump. The fast idle relay shown in the second pic serves as the fuel pump relay on those models. If the wires on that plug happen to be pink/black stripe and brown/white stripe, they are connected to the relay.

Hope this helps

it just so happens, that when we swapped out the 305 for the new 383, we tried removing all the wires we could. we unplugged the computer totally (2 black clips) and since everything was out already, that huge loom of wires just came right out...easiest wiring i have ever done haha. i will probably need to get different gages for the dash, but id rather get new gages than have a 1 inch thick loom of wire all over the engine compartment. we are also going to need to run some new hot lines and such, but thats not hard and we can route those any way we want to!
