1986 GL Wagon SPFI conversion under way! New carb f/s

[firehawk618]

Welp here's a little background and my goals.

I recently picked up an 86' GL Wagon 4x4 D/R 5 speed for cheap. Considering it's 30 years old it's in pretty damned good shape!  The paint is faded but all there.  I'm sure a good buffing would bring it back to life if I wanted to.  The interior is in pretty good shape.  Drivers seat is a little flattened out but this is to be expected. 

 

The Hitachi that was on it was dead.  I mean it was near impossible to drive.

I was going to go through it and use it but upon close inspection I could see the throttle shaft was VERY loose.  No saving this thing.

I picked up a 2nd Hitachi from a guy parting his blown engine car out for cheap.

Threw it on and it ran but still crap!

Picked up a 32/36 + Toyota adapter and she lives!


Fast forward a week and I came across a 1988 DL wagon and was told I could have whatever I wanted off it soooooo I pulled off the whole SPFI intake and related parts.  Instead of pulling the whole harness I instead pulled the engine harness and cut off after the connectors that go into the dash.

What a nightmare the whole thing would be to pull.  All once piece it appears.

I will instead just wire in the required components for the EFI to run.  I don't care about CEL light / codes so I am not wiring up the EGR, EVAP etc etc.  Just the throttle body, temp sensor, MAF sensor, distributor, coil and fuel pump.

My ultimate goal is 4" lift, 235/75/15 wheels and possibly a welded rear differential.  I will be hitting walker valley etc etc.

Hauling garbage and big items is also on this car's to do list!

Anyhow I'm looking forward to getting this all slapped in and running within the next couple weeks.

I am also considering yanking the SPFI heads off that car to clean up and have ready for when I pull this engine and install a new clutch *it's weak*, seal up the engine etc etc.

If anyone in the Seattle area is interested in a complete basically brand new 32/36 that's ready to bolt on let me know via email at fireahwk618@gmail.com  I just paid $145 for the carb *manual choke*, $45 for the Toyota one piece adapter.

I would let it go for $160 and YOU can come hear it run and go for a ride with me.

I never hooked up the choke so it's a cold blooded girl but runs pretty good once it warms just a touch.

Couple of questions regarding the ECU that I'm using.

I'm taking the extra wires off the connectors and there's a couple that I'd like some clarification on.

Pin 10, 11 and 12.  They're all listed as "Line End Cord Output"   
What are these?

Pin 22 "car speed sensor"  Does my cluster have a speed output that I can feed this wire or is it even necessary?  What's the consequence of just not hooking it up?  I don't care about CEL and codes.  When I had my cluster apart recently to replace the faulty speedometer I saw nothing on the speedometer itself that would be able to feed this. The head was purely mechanical as far as I could see.  Perhaps the ECU would make the idle "hang" at higher rpm's a bit if the car is still moving as lots of cars do for emissions?

Pin 28 "Self Shutoff Signal"  What is this?

 

Pin 33 "49 State / Cal Identification"  What is this?

Thanks for any help folks!

I know you aren't using the whole loom but this PDF may help you 

http://d01.megashares.com/dl/yvPza8n/EA81_SPI_guide.pdf

 

It is the guide to putting the SPFI on an EA81, yes I know you are putting it on an EA82 but it may help you.

I do appreciate the link!

I finally found a full schematic that I was able to trace the wires I had questioned above and have answered my own questions on those.
