Hello people i have just purchased a greddy turbo timer, i have installed it no probs for the actual turbo timer but need to connect the other wire to the speed wire in the ecu.
This will then enable me to record 0 to 60s etc does any one know which wire i need to cut, the turbo timer manual just says the speed wire which i presume is some where in the ecu any ideas ? thanks

 

There are two cables going out with speedo cable - they probably go to ECu and have speed signal. But I am not sure about it.

 

which car lee? not all ford have an electronic speed sensor as the speedo is mostly cable driven. even if it does, it is probbaly just a pulsed signal from the sensor to the ecu which may or may not be compatible with your turbo timer.

 

hello thanks for your reply the car is a rwd on the g plate. The cable to the speedo is not the one cos as you say it is hard wired.
it is some where in ecu, im not too bothered about fitting it just would be nice thanks

 

what a rwd sierra on a g-plate? in that case, there is definitely no electronic speed signal on the engine ecu. the abs ecu must calculate speed from the abs sensors, but i don't know if you can access it, or what form it is in

 

ok thanks for your help. You dont know anywhere i can get some rs 7 spokes from, im been into ford and he reckons they dont make them no more. I need some asap cos my car looks a bit dull with the snow flakes on thanks !

 

i got mine from ford (german dealer), came in a couple of days. last i heard, the warehouse in cologne had some still.

if you've got 4 pots on the front, you'll need 5mm spacers as well (just on the front) so that the inside face of the spokes clears the caliper.
