VTS Owners With Crossover Loom (2000)...

[Jim-Bob]

I'm in need of your help!

Swapped my 3 plug loom for a crossover loom and i've got to the rad/fan and its causing some mega headaches :(

Basically i need some very kind people to have a good nose around their engine and grab some pics of all the fan/rad wiring so i can work out what goes where and if i keep the 3 plug fan, or need a single plug version, or find out that crossover looms had their own type...

Currently the rad sensor is connected to one of the realys in the fan surround and there is lots of wires linking a second relay and also 2 wires heading off into the large engine bay fuse box and another to earth...

Now i don't know if this is the same for crossover looms as i have a small squareish black connector with a single wre going to it which i believe is fan related and also have this connector which i have no home for:

Any help would be great as it's driving me mad trying to find out what this unique loom uses...

That connector is the interia switch connector. You want to connect it or bridge the 2 parts.

Iirc the crossover vs the 3 plug looms had hte same connector but the wiring was pretty different - I could be wrong but i dont think what you are doing is going to work without swapping some wires around

the rad fan is a 5 wire switch. I suspect some of the pins were for the unfilled 2nd fan option on UK cars. Either way, you just need a switch to trigger a relay that powers the fan.

This can be in the form of fitting a mk1 rad that has space for the blue fan switch, or making a cirucit that triggers off one of the temp senders, a switch on the dash or the aftermarket thermostatic switches. that go into the pipe.

Oh yeh forgot that the inertia wasn't connected...

My rad currently has a single blue sensor in it?

What triggers the 3 plug fans? Are the cables leading to the fusebox just for power?

And how are mk1 fans triggered?

Just trying to work out how everything works then I can come up with a solution :y:

Nobody feeling the love tonight? :(

Need to get this sorted so i can get the car running asap!

Anyone? :hug:

what do you want to know?
mk1 fans are triggered by a blue fan sender on rad(under upper rad pipe) irrc

[ryanmt]

^^ mk1 is a temp off the radiator separate of the ecu., mk2 the ecu turns it on depending on itself.

I wouldnt worry too much about the rad fan in the middle of winter mate, get it running first.

Just want to know what the wiring looks like, can't find a plug to connect the loom to the rad sensor? :panic:

I haven't got the rad sensor or fan connected though mate...however i do have a second fan on a switch...just want an automatic one plumbed in...

Hi mate, I'll have a look and take some pics for you tomorrow mate.

What do you need me to look for mate? :)

[Jim-Bob]

Cheers mate!

Where the rad sensor is conencted too and what wiring the fan has is what i need...so anything that is rad/fan related photograph please :)

James

not 100%
but if u want the mk1 wiring
its a blue plug(alot bigger than the one u pictured
or it could be a brown plug that goes into the thermostat housing.....

[jsdvtr]

I have on mine 2 fans and 1 was working with the ecu but has stopped working for some reason and other is connected to the sensor in the rad just by 2 wires with a fuse which goes into fusebox. This was done by the guy who did my engine swap though.

[Jim-Bob]

Been out and stripped back the the material wrapping the fan loom and dug out my Haynes bible and set to work trying to see if i can convert the 3-plug set-up to single/crossover...

I believe it is possible as shown below:

The yellow shows my proposed re-wire with the original beside it, and the single spped i'm aiming for, the wire numbers/colours are the same so this should work, should it not?

This is done on the following assumptions:
- Engine Fan Switch = radiator sensor
- Single Speed Fan = single plug loom
- Twin Speed Fan = 3 plug fan

Are these assumptions correct? If not what should they be?


And the one piece i can't figure out if where the small black connector goes? It's the one by the plug on the passenger rear arch, which only has a single wire runnng to it? If someone could explain what that does, hopefully i'll have the full picture at last!


Cheers for all the help so far though!

This is the black connector i mentioned above:

Can anyone help me out?


James

[Jim-Bob]

Mr wigmore did you get chance to grab any photo's over the weekend?


Or anyone else for that matter?


Would really like to get this all cleared up now...


James

[Sophia_Bush]

is it just the fan now?

[Jim-Bob]

is it just the fan now?

Yes it is Gav, but the rad may need to be changed depending on how the fan is controlled...

James

[Sophia_Bush]

3plug is ecu controlled single plug is via rad switch your running pred so none ecu control

[Jim-Bob]

Ok mate, in the wiring diagrams above does that mean i need to rewire the fan as the per the "single speed fan" diagram? (drawn this in yellow on what i believe is in the three plug set-up?)

Is the "engine fan switch" the sensor in the rad? If so is it the one that all rads have facing towards the bulkhead?


James

[Jim-Bob]

Still not got to the bottom of this, anyone got any more info/pics of the cooling set-up on a crossover VTS?

James

sorry to hi jack the thread but did you re-wire your Mulity plug? or was it plug and play apart from the rad?

It's all plug and play mate, fan just needed to be converted to the mk1 setup I eventually found out :y:

James

how did you get the fans to work?

[blackie_2k5]

he converted to the mk1 fan set up as said..

[LeandroX]

yes... but what needs to be done specifically?
