1993 loom to 1998 loom. Help

[Paul Smith]

I have part of my 93 loom running from my omex I'm looking to join with a 98 micra loom but they are completely different. They are found on the side of a standard ecu. Any idea what colors do what and or would marry to each other.
I know it's a big ask but I'm sure we can work it out...

Thanks

First pic of 4 connectors (only 3 big ones were plugged in) need to work with the 2 other ones from a standard 98 micra

i think you would have to cross reference the non nats diags with the pdf manual diags paul

 

[Paul Smith]

Using auto data it says the ecu pins and cable colours are the same 93 to 2000. This isn't right because these two looms are very different

 

[frank]

yes i know, that download pdf has a mass of diags tho eh

 

[Paul Smith]

Which pdf download? Where can I download it from?

 

[frank]

posted on here a while back mate

[Paul Smith]

Cool thank you. Is the eccs wiring diagram the same as the nats?
I.e different to my auto data.

Thanks again

 

[frank]

the nats and pre nats differ on the ecu plug by about 5 wires iirc paul, but the smaller black/white/brown connectors will be the ones you need to figure out tho eh

 

[Paul Smith]

There the ones lol little buggers. Just need to find them on these diagrams

 

[Paul Smith]

Has anyone previously worked out these cables?
Someone must have mixed and matched looms at some point.

Noddie had sent me over the diagrams for the full looms if thats any use to you bud,pm me your email & il send that over

 

[Paul Smith]

I have matched up on paper the way to go. Does anyone have a list of which pin does what on a nats micra?

 

[Paul Smith]

Pin 106 fuel pump relay on the nats ecu does not appear on the non nats ecu?

 

[Paul Smith]

Any idea why? Where is the fuel relay on the nats micra

 

[frank]

hav,nt you got the nats and no-nats diags paul ?

 

[Paul Smith]

I do but unsure where the fuel relay in the 98 is. The wiring diagrams are good but not sure where in the car the relay is. On the 93 it's by your right foot behind the cover. I believe in the 98 it's one of them on the fuse box but there are 5 so not sure which one it is.
Once I've located it I can work out where and how to bring the omex part in to play

 

[Paul Smith]

I need to work out which ignition cable to link up to as well

 

[frank]

the relay is in the pillar there on the preface nats paul, its the facelift k11,s that had a lot of wiring changes eh (post 98)

 

[Paul Smith]

It's the face lift I need to find it on. Compared to my 93 wiring wise there are massive changes lol

 

[Paul Smith]

Any ideas with the brown connector. On the wiring diagrams it has 3 or 4 wires from it. However mine has 12. Of which none have married up to the nats micra yet. Also I have 4 cables from the nats micra left and in total I have 25 from the 93 micra left. Very odd.
On the nats wiring diagram it shows 4 connectors but I only seem to have 2???

 

[Paul Smith]

I'm guessing the 2 missing connectors hold the key lol

 

[frank]

you,ll probably find that the coilpack looms are more relevant to yours paul (electrical 2 pdf page 400 ish)

 

[Paul Smith]

Thanks mate I'll look first thing in the morning

 

[frank]

Thanks mate I'll look first thing in the morning

that ecu loom has 2 plugs (like yours), a 13 wire plug and a 5 wire plug paul, the preface diag has a 16 wire plug, a 3 wire plug and a 9 wire plug

 

[Paul Smith]

Cheers mate. So on the face lift have they by past the ecu for 9 wires?

 

[frank]

nah, on the facelift diag it shows 2 smaller plugs near the big ecu plug, and on the pre-face diag 3 smaller plugs.
so if the later diag colours match to your 12 wire plug you,re sorted

 

[Paul Smith]

Had a night off the car yesterday. So going to have another go tonight. See if I can find these other 2 small connectors

nah, these 2 paul ^

 

[Paul Smith]

Following the wiring diagrams most of those 2 from the nats micra have hooked up to the black connector?

 

[frank]

take no notice of the colour eh, if you have 2 connectors, then its more likely to tally with the coilpack loom diags (which has 2 connectors also)

 

[Paul Smith]

I've been a plank lol focusing on the cables running from connectors in to the car. Where as I should have looked at what connectors are actually used by the omex. The brown connector for example only uses 3 wires but has loads out the back.

I'm happier now because there seems to be the right amount left lol

 

[Paul Smith]

It's no good lol I need to find a wiring diagram to match the 98. I've used the nats ones but it's still taking me off to connections I don't have. The colours don't match up either on these last few lol
