I replaced the EFI wiring loom a couple of weeks ago and everything runs fine although there was a spare connector which wasnt on the old loom. Just wondering if someone might shed some light on why it was there?

 

 

Thanks guys.

looks like boost safety solenoid valve plug

usually bypassed with a booost controller

hmm i have no boost controller. I find it wierd that this plug wasnt on the original loom was is on this loom.

nobody else got any ideas?

I cant see anything the same as that at the rear of mine but it does look the same as a boost solenoid plug.

I'll have to go and have a look at mine, i can't think what's there to be honest without looking

those 3 plugs all come off the loom in the same place, (behind my hand!) on my old loom there are just the two rounded plugs, not this black square one.

wastegate actuator plug

 

the other two you are holding is o2&vvt leads

Thanks guys for all the help :)

but this is really bugging me now...

 

I have located the wastegate actuator plug further forward on the loom.

This plug is identical.

See schematic i just created below, mystery plug is marked red:

 

(I believe the loom may be for LHD as there is excess at the battery and i had to extend the PRVR solenoid lead.)

 

 

Maybe a useful pic for people trying to find connectors, might have a go at tidying it up a bit ;)

ok after much searching i believe this is:

 

Exhaust Gas Temp Sensor

 

for a California model Zed, i believe no other zed's have this sensor hence nowhere to plug it on my Jap-Spec :)

 

Possibly useful advice if anyone else changes their harness and wonders what it is for! Also you now have a nice EFI schematic if you want to save it :)

 

(updated the above picture)

hiya i have the same plug that isnt pluged in and posted this some time ago and no body could give me an answer, but the car is fine and no faults found
