87RockTPI

So I'm getting the car up and running, it's been sitting awhile and am confused where this plugs into and what it does.
Was putting headers on the car a few years back and disconnected things to get them to fit. Got most of it plugged back in however I can't figure out where the pictured harness belongs.

Thanks for your help guys definitely need assistance here. I do have a shop manual the dealers used but am having trouble locating it.

Also where does this go as well.

I can't see the first picture well enough to tell you, the second one is a vacuum line to the heater control valve.

Looks like it may have made a long trip but possibly the EGR solenoid plug. The intake temperature sensor is the closest thing I can think of over there but I recall that being a different type of plug.

Damnit lol, I'm trying to remember where it is or if it was removed during the installation of the headers. Will the car run without it if I can't figure it out? I need to move it to a storage facility

The egr doesn't NEED to function to drive it. It'll pop a code eventually if left that way though. Plug that vacuum line too.

I'm gonna eat dinner, as soon as I'm done I'll go back down and check the egr.

I thought that was mounted up by the ignition coil? Maybe I'm thinking of an 1986

egr solenoid is next to the coil.

Oh my car is an 87 305 TPI, forgot to mention that at beginning of thread

had two wires. One os black. The other is pink with a black stripe. Found the service manual, according to control map it's showing it possibly being canister purge

I'm wondering if it's just not used, or if it hooked up to something originally when before the msd was installed

Are you sure one isn't gray? The egr solenoid has a gray one and pink/blk one.

I don't think it's the egr solenoid, that looks to be more toward the front of the car. It's kinda cool working on it again, becoming familiar with it again. Although it is a pain to work on. I just need it to go 16 miles to storage while I'm waiting to take possession of the new house.
Looking forward to that. Has a 4 car garage 20 x 50 deep.

As far as your question on wire color it might be gray, ran out of steam, worked all day and need to be in early tomorrow. Will hopefully fire it up tomorrow, just need to route a plug wire away from the header, tie a couple rubber pieces together for the AIR tubes and drop in the battery

Egr solenoid is at the back just under the coil......

87RockTPI

I checked that, it's all hooked up and intact.

I have a vague memory of people who had a mystery plug that went to nothing even from the factory. Did a search.. https://www.thirdgen.org/forums/tech...g-my-87-a.html

87RockTPI

That's what it looks like however it's in a different location from that.

I wonder if it had something to do with the transmission? Being that the tranmission was stand alone from the computer in 87 maybe it was just not used that year.

87RockTPI

i can't find where the vacuum line hooks too am hoping for help

87RockTPI

Just found it lol

Was it there?

87RockTPI

Yep, found it in the service manual. That thing is great, I spent a lot of money on it back in the day. My dad told me but this d@$n thing you'll thank me someday.

That thing has saved my butt numerous times with the jump charts and everything

Car started up once the air got out of the line from changing the fuel filter. Second attempt and it started just like it did years ago.
Thanks for your assistance

You're welcome. Good luck with that mega garage you got coming! I'm still looking for my own.
