[KesekiSupra]

as the title says. i would like to have a wiring diagram for a 4me mk1 ecu. or all the wiring diagrams would be even better, but just the ecu would be fine. tia

Shawn & Keseki,

Partial good news!!!

Electrical wiring diagrams are in the 79 - 81 Haynes MKI manual (I don't even want to know what the crappy 79 - 92 Haynes manual has). The Haynes MKI manual has ALL THREE wiring diagrams for 79, 80 & 81.

ECU pinouts: "Hopefully" the pinouts are the same between the 79 & 80 4ME. Best news: Found the ECU pinouts in the 4ME EFI supplement. I also confirmed that the 5ME EFI supplement also has the ECU pinouts.

Still trying to figure out how to use my GF's scanner. Digi cam is more convenient, but I won't get it back till late Thursday night.

fantastic! the pin out will make the project much easier :)

[CJSREDPRA]

YAY!!!!

My GF is back home & so is the digi cam!!!!

From the EFI manuals. 4ME ECU pinout: For clarity purposes, this is from the "connector plug" side, not the ECU side.

From doing a side by side comparison of the pictures, it looks like the 5ME ECU pinout is identical!!!

Keseki, there are a number of 4M, 5M EFI supplements on eBay if needed.

I have the EFI electrical wiring if somebody need a copy let me know. I can take a photo and send it on an Email.

[KesekiSupra]

does it have a chart to say wat all the abbreviations are? =\

[CJSREDPRA]

Just got done......... looking at ALL 100 pages....... in the 4ME EFI supplement..

No chart.

Best I can come up with, is the wiring diagram for the EFI system. Will have to try & get a picture of it. The pic will be rather large....

Can I just shoot you now?????:eek4dance:

100 pages..... :mm_twak:

[KesekiSupra]

=\, dont worry about it then ill buy the haynes manual and look at it myself. i dont want u to do work on my part. thanks anyways, theres like 4 or 5 of those pin's that im wondering wat they are. ill just post them up and see if anyone has a clue perhaps. they're:

(+B) - Main relay or battery positive from fuse??
(Vb) - Has a b in it, so same thing as above
(IG)
(TL) - No clue on this one
(PSW) - thinking neutral safety switch

[CJSREDPRA]

Since I'm in a chipper mood & have time to kill... I snapped a pic of the EFI wiring diagram from the 4ME EFI manual..

WARNING.... Large picture!!!!!
