In the process of finishing my wiring harness for my spfi swap on the hatch. The only problem I'm having is figuring out which wires go to which fuse or relay on the Mitsubishi relay box.

 

If anyone has some pictures that'd be great, my fuse box doesn't have 2 15 amp fuses or a fusible link like shown in GD's write up, but was it came from another FI swapped ea81 that worked.

 

I'll have pics here shortly once it's light out...

 

Thanks

Also, if anyone has an engine bay shot or two of their spfi swap feel free to post it lol!

 

Trying to get as much advice/ideas as possible other than GD's write up

Here's my Mitsubishi fuse box, I know which wires go to the fuse box but not where they should connect to as they aren't a simple color match

Also which one is the fuel feed and fuel return so I don't hook em up backwards lol

Here are the only shots of my old setup that I can find so far. It's kind of a mess here, but it was running at this point. I hope it helps a little. Good Luck!

This might help a bit, thanks again. Say, is the fuel line behind the filter going into the cabin ?

It's a small metal line that I used for a fuel return. It was unused on my car. It runs to the back with the rest of the lines in that area. I used a brass adapter to make it work. I also replaced every fuel hose on the car front to back, especially the old nasty ones under the back with high pressure fuel injection grade hose.

Gotcha, so that little line Is the fuel return? The one to left of booster. And the other is a fuel feed vacuum line I'm assuming for vapor canister?

 

What's the black plug where the red/black wire from the fuse box is going to?

Hmmm that was about five years ago, foggy. Let me shake my brain a little more...

I can see that the big white wire goes to the battery. And I believe the two small green wires connected to the black one left on the fuse box goes to the battery as well.

 

It looks like the red/black one goes to that black plug. The red/white one looks like it goes back into the cabin ? Im assuming for the ignition hot in start only wire. ?

 

Cant figure out where the black & red 14-16 gauge wires spliced into the one connector go ..

Zoomed in a bit. It looks like the two 16 gauge wires spliced into the connector go to that ground wire right there on top of the passenger strut tower ..

That looks right, that connector probably got chopped at a later point I would think. I pretty sure I was using a heated oxygen sensor. There is probably an extra pair of wires in those photos for that too. There is an oxygen sensor ground wire too as I recall connected in the spare tire area.

I would think so too, but what wires are going to that connector ? It also looks like that ground wire on the passenger strut tower is spliced into something else as wel ..

I'm thinking maybe that's where I picked up the tach signal but I can't remember for sure.

Hmm, well, I think ill just connect what I can & go from there. Thanks again jeff

I cant copy & paste the pictures from GD's spfi write up but I think the red 12 gauge wire tapped into the ignition plug shown on page 51 is the red/white wire from the fuse box shown going into the cabin in crazyeights pictures.

 

The red 12 gauge wire for the fusible link in the harness must go to the other?

Hey Skylar,

I found this site that has Snowman's spfi guide that may help clear some stuff up for you.

I believe it was about converting EA82 carbed engines but the electrical should apply.

Thanks Abe, was trying to click on the link for Snowmans write up in GD's write up but wouldn't work.. hopefully I can get some answers here

Hey Jeff, so how did You use the little 1/4" line for the return? The flow of the filter goes towards the throttle body..

I got it to crank over!! I'm getting fuel, But I don't think I'm getting spark. Don't have someone here to check while I crank it over. Coil is grounded to block, but I don't have a ground on the actual bracket?

 

Do I run a ground from the bracket to the block as well?

Here's my coil bracket,I took the coil out until I find a longer wire for it,

Definitely no spark, pulled a plug and its wet with fuel. I also cranked it while the plug was in the wire touching something metal and still no spark.

 

I ran a wire from the coil bracket to the block but that didnt do anything either.

 

Pretty sure my starter signal wire is hooked up to the right ignition switch wire too.

 

I wanna hear the thing run im so close !!

What exactly are you looking for as far as pics go? I have a spfi swapped car if you need some photos of anything specific. I also have some of GD's original write up on my computer of just the wiring section, no pics, but I had to go back to that one page pretty often in order to get everything wired up correctly. The swap takes some time, but it is worth it when it's done, hang in there!  

Basically I need to know which wires from the harness go to the Mitsubishi fuse. I have them hooked up now. But I am not getting spark. I believe everything is grounded. The only wires I do not have hooked upped are the wires for the neutral switch for the transmission, the wire for the ecs light, and the speed sensor wire that goes to the clutch pedal switch. But none of those should factor in making it spark.

 

If you have any pictures of your coil setup, or if you're using the Mitsubishi AC fuse box as well abd have some of that that'd be awesome.
