help me figure out this wiring please

[me217]

hey can anyone help me. i bought an ecu and wiring loom for what is meant to be for a 4agze map. now i know the ecu is correct but i'm not sure if the loom is. 2 of the plugs fit into the ecu but the 3rd is huge compared to it. ill post up pics shortly. i really hope the loom is correct cause i've been looking for ages for one. or i hope i can make it work at least.

Usually there are 2x plugs on the engine harness and then the 3rd plug is for the body harness and not part of the engine loom.

just moving this to the correct area

Yup as mentioned, looks like you are missing the 3rd plug which is normally part of the body harness.. Those other plugs are not for the ecu.

Being a MAP 4AGZE, I assume it's from a Levin? Those big plugs attach to the body wiring just under the stereo in the dash. You need the third plug that is a part of the dash loom (as mentioned above).

I have a complete Levin dash loom sitting here next to me, but it is from a 20v silvertop model. It has the plug that fits the ECU where you need it, but will probably need a bit of repinning to wire it up right to suit the 4AGZE, nothing too major, I can have a look at my GZE loom and let you know the differences. It also has the sockets for the two plugs you can't fit into the ECU that got you confused.

PM me if you want it. (I'm in Brisbane). It came out of a Levin that I am sticking a 4AGZE into from another Levin, so it's surplus to my needs.

Thanks everyone. What dash wiring would I actually need. Btw I've done an engine conversion before but in a Suzuki and i used a half cut. This time I'm doin it from scratch in a ta22 so I gotta work out wiring, parts and everything else. But at least I have the base idea. Ta22. 4agze. Niteparts bellhousing and w58 box. I just need the bell housing and the box and I'm almost there

One other question what's the best way to hook up the speed sensor for the engine. When I did the Sierra conversion i could fit the vss in the Sierra cluster but I don't think that's possible in an old ta22 swagman and I'd prefer to keep it looking original as possible
