Any help much appreciated.BARRY IN SA.

Hi Mate, 

i cant say specifically if the BF has the same VSS input as the BA ecu does, but it wont hurt to just look over the ecu and see if the pins free.

PCM Pin B7……...................……….Vehicle Speed Signal VSS

 

what sort of speed input do you have on the coaster? will need to be a 5v square wave type.

shiftkitsaustralia helped me by making a box that converted the abs AC signal to a square wave signal for the ba VSS input, this is how i was able to get speed input from a car without ABS module from factory.

for anyone wondering in future, all ba and bf ecu accept vss in on b7 with source as oss and vid disabled.

they also accept ac sine wave on this input without a module to convert it.

How do you mean?

i have just put a e series rear ext housing on a  btr transmission 

to get a speed signal as they have put it on the front wheel 

with a abs ring.and iam trying to wire it up and 

get it to work in the pcmtec software ...

Have a look for an unused 3 pin connector near the other gearbox wiring connectors that matches the Ford speedo transducer. It's usually got a plastic plug in it for protection & is taped to the rest of the loom.
