traction control/ electric speedo

[stappogsi]

where is the traction control sensor on a v6 gearbox? and what colour are the wires. also where is the speedo sensor on the box and how do i wire it up if the car origionally had mechanical one?

What Car?

On Cavalier/Calibra the TC ECU is in the passengers sill panel.

On Vectra/Omega it's part of the ABS ECU.

Speed sensors are on all 4 wheels (on rear diff for omega)

iv put a v6 into my astra gsi out of a calibra

[Mark T]

if your GSI had TC, then it will have the same ECU as the V6 in the passenger sill panel.

You just need to connect up the TC inputs to the engine ECU (on the small connector in the footwell)

[stappogsi]

do you know about the speedo?

[stappogsi]

btt

Speedo is derived from the ABS computer. Same in any car with ABS, or any Vauxhall after 2001 (they use a single ABS hub to get speedo)

[Mark T]

If you have an older GSI that had mechanical clocks, the speed signal won't work from the ABS ECU as you'll have 40 tooth CVs not 29.

[stappogsi]

ho how can i do it? how did you do yours in your gte mate?

[Mark T]

I have 29 tooth rear hubs and front shafts.

[Allan_100]

think your gonna have to get a mechanical set of clocks or a transducer from an astra GTE with didgi clocks and see if you can wire it up to the elec speed. I sure it can be done as I am looking into that so I can remove my ABS as its buggered

[Mark T]

The F25 doesn't have a Speedo output that's his problem.

[Allan_100]

I thought they had the output but it was just blocked up. Will look into it further. I havent got an F25 on my cav V6 so cant look. Should be some sort of little cover thing on top of the diff housing. Will let you know what I find out

[Mark T]

nope.

There's no facility on the crownwheel for a speedo drive.

[stappogsi]

iv got the calibra drive shafts in the front but astra hubs on back. i really need this doing as its on the road now. what bits will i need the v6 clocks and ecu just wiring it up or what ever?

[jem-autos.com]

ive got mk2 astra with v6 engine 43 teeth abs rings but on the gear box side of short shaft i had a "sholder" machined on it and fitted a 29 tooth abs ring and made a bracket to hold a abs sensor just for my speedo
