16v Single Plug/3 Plug Differences

9th September 2010, 18:24

Brought a new loom for my car to run a single plug loom, but the current loom is a 3 plug one...

Which (if any) sensors are different?

Are the alternators the same?

I think most of the sensors will be different.
You've got a lot of work to do

I think the alternators are the same though!

I know its going to be a mission, just need to know any additional bits i'll require

I'd imagine.. all the sensors (more or less)
Including the throttle body.. so you'd probably be best buying the inlet setup from a Mk1...

Then i guess you'll loose a lambda sensor, and you'll have to try and get it to join up with the interior loom!

Straight fit onto the interior loom so thats not an issue...second lambda isn't connected anyway, rewired to read 0

So just engine sensors i guess?

Can anyone give a definitive list before i go buying new everything?

I think it'll be tricky tbh.. the connectors vary quite a lot.. I've had two looms, both from a 2003 VTR, and the water temperature sensor was different on both.

You're probably best off going down to a french car scrapyard and matching up sensors with the loom.

Good idea...shame i don't have any french car breakers round here

Could try the local scrappy not sure whats in there though...

Yeh, worth a look! Buying new would be too expensive.. and it'd be pretty tricky to get all the right connectors otherwise.

Or if you knew what you were doing you could use the existing sensors and splice the connectors onto the loom?

Not sure what you're doing really.. so i dunno if that's an option!

Converting to single plug to run the Predator

Don't want to go splicing connectors as i'd like the loom complete to sell on

How much is the loom worth?
It might work out cheaper to sacrifice the loom.. But i guess it wouldn't be so neat.

So have you already got a Mk1 interior loom or something?

9th September 2010, 19:14

I been thinking of doing this too, i know when i put a mk1 tb on my mk2 engine & loom it was only the tps sensor had a different one on which my mate went and got a different plug from another loom.

Might be worth gettig a mk1 loom with the same sensors.

9th September 2010, 21:30

i have 2 mk1 VTS engine's at the moment, was gonna say you could pop down and match up the sensors as i have a mk2 shell with mk1 engine, also have single plug loom with digital dials

But realised your quite far away

, might have a throttle body set-up off a mk1 VTS engine you could have? gotta look for it though

I can travel for cheap parts! Lol

Are you about on Sunday?

How much would you be after if I came and picked as many or all of the connectors that fit the loom?

Mk2 loom will have connections for a few more sensors, an oil pressure i think or oil level or somthing and a knock sensor irc

Guess I just leave them in place but not connected then?

3 plug main plug is 21 pin as aposed to 19 pin. Sensors on the throttle body have different connections, as are most of them And the dials run off the ECU.

Both looms have oil temp/level and knock sensor just uses different plug heads/sensors.

11th September 2010, 18:37

I have a spare 3 plug loom from a 51 plate VTS

Some of the plugs are damaged so its ideal for butchering.

PM if interested.

I've been told everything should fit now as this is a crossover loom, but I've not checked everything yet so I'll let you know tomorrow night once I've had a play about!

alternators are different....
sensors:
some of the early early map sensors are different to the newer ones
icv will be fine.
tps is different...
rest of throttle body sensors are fine.

one of the thermostat sensors is different
the oil pressure on front of block is different.
knock sensor-not sure.

and how did u do this
"second lambda isn't connected anyway, rewired to read 0 "

12th September 2010, 22:37

as said near everything is the same i dunno what sensors are going off the dials but going on experience with mine I am running an analogue dial ecu in a digi dial ca with no difference

the main as i said is getting the right loom with the right sized multiplug on the passenger side wing

Cheers mate, loom was the wrong one in the end so I've had to start the search all over again

Looks like I need a trip to the scrappy for some new sensors and alternator

The lambda was modded before I brought the car, it's still tucked up under the car so not quite sure what's been done to it? When I jack the car up again I'll see if there's anything obvious if not I'll have a chat to ghe previous owner and let you know

It will be a wait and see job I guess Gav, if it don't fit it needs changing lol

I was told this one was correct but compared them and the plugs were way different, think I've found the correct one now though, awaiting pics to confirm

In comparison how does something like omex 600 work with custom loom as you still use existing engine loom?

Just wundering whether its works messing about with a single plug loom for pred or work paying the extra for a better ecu and be easier to connect to car, etc.

Not sure the Omex is better than the predator?

The Omex plus loom and mapping will set you back the best part of £1300 new, I got the predator with mapping software etc for £300, so changing a loom and maybe a few sensors to save the best part of a grand is a no brained IMO

Predator will be plug and play once the loom is changed too

James

13th September 2010, 13:19

U need alternator, injector loom and cts off the top of my head. I hav all 3 at home coincidentally

I put a 3 plug loom onto a crossover engine and they were what came off it.

13th September 2010, 13:53

You dont need to change the alt, just the wires

13th September 2010, 13:56

My 3 plug alt had a ring connector and a plu connector, the plug had 2 wires into it. My single plug loom had one wire which I can see you being able to put the plug connector onto?

13th September 2010, 14:25

If your fitting a single plug loom onto a 3 plug engine you just use one of the pins. Cant remember what the other is.

Well i want to do the same as i want the pred too as will save some money. Been thinking about chaging looms for abit as started the same thread abit ago but with not many replys.

Another thing that might be useful, not sure but worth saying about. You know saying has to be the right plug to connect to where i goes by fusebox. Would it be worth say putting fusebox inside car and getting rid of the plugs and just connecting the wires up to each other or putting the same plug from the fusebox to connect to engine loom.

If that makes sense.

Note sure its a simple for for one crossover i don't think mate

Also it would be a bit of a nightmare as you get very little slack on the loom, chance of a dodgy connection grows massively when everything is individual too...

Tbh searching for the correct loom and fitting it is problem the quickest and simplest option (relatively cheap too as you can sell on what you remove to cover the cost as people are always after looms/sensors

)

Think i have most things lined up now, all i'm short of is the TPS and oil pressure/temperature, so if anyone has either of these from the ac rossover loom let me know!

Cool, you'll have to let me know how it goes when swapping the looms over and maybe pics of the loom, etc as very interested in how it goes as wanting to do the same when start getting more power out of the engine.

Will do mate, just make sure you thoroughly check the loom is the correct one before buying

ive just done this but the other way round, i bought a vtr mk 2 engine with a three plug loom, fitted the engine and used my original mk1 1 plug loom

How did you get on with it?
