Question about injector/engine loom


Recommended Posts

In theory, what would happen if you swapped injector connections over via the loom eg

swapping injector #2 for injector #4 on the wiring/ecu side? is it detrimental? will it affect performance? could it blow an engine?

The only reason im asking this is on my 8s ecu the pinouts are in different places and the injectors connect but according to the diagram; its all screwed up

injector 4                      Injector 3

                 COILPACK                                     (looking a the engine from the top)

injector 2                      Injector 1

it has the original ecu (according to the previous owner) in it, it just doesn't all plug in how it should according to the 1998 wiring diagram, thats whats worrying me

(looking on google it seems 8s is the ecu for a 1998 right ;/)

an example is:

the yellow/red common wire in all the injector plugs is meant to connect to pin 1 but it connects to pin 4, swapping with the pin of the ignition coil :/

how could i solve this issue?

(phoned the previous owner and he insisted that i was "worrying too much and its a standard loom with standard ecu"

I think the 8s ecu is a uk version Is yours a v3/v4 uk car ?

Cos if yours is a jdm there's a few differences in pins

Cam ,crank and possibly a fuel pump wire (to do with the UK having a imoblizer )

But if you've got the standard loom the standard ecu should be plug n play

If it's not broke .....upgrade it 😊

Yeh it's UK version but the question is, why isn't the pins matching Vs the 1998 wiring diagram ? According to the book, I'm gonna go out with my muktimeter and try figure this out!!

its all good @savage bulldogs i was reading the loom incorrectly, injector are all in order and the loom is all correctly pined at the harness/ecu, tomorrow ill be taking that abc chip out and burning it!

Trust me I've made a few mistakes along the Way [emoji57]

But a man who has never made mistakes has probably never really made anything [emoji6]

How close are you to firing it up ?

Should be firing her up tomorrow sav, but I don't have gaskets for the headers:(

Shame your not closer ,i've probably got some[emoji57]

if you phone luke @ ipc first thing you'll have em by lunchtime tomorrow 😉

Oh make sure you use genuine upipe gaskets cos it will blow like a cheap hoe otherwise

Luke@icp? :D info pls sav mate 😂 trying to also figure that angled nipple on charcoal canister and see where that plugs in! (I'm scared I might have to pull manifold again :()

In this pic of the top of the canister

9974A9B2-orig_zpsfc5e6e4f.jpg

the big bore red pipe is the same one on the boost control bracket (in my earlier pic)

The middle black vac pipe ( that has a 1 way grey plastic valve in) goes to the clostest vapour hardline ( metal pipes attached to the fuel rails)

The other small bore red pipe goes to the furthest away from the canister hard line .

Hope that makes sense lol

If it's not broke .....upgrade it 😊
