Rev Counter

[dazzler24]

ive got a mk5 1.6 zetec wiyhout the rev counter(it has the car symbol instead)how easy would it be to fit speedo unit with rev counter to my car.ive heard its a straight swap?is this true and how easy is it to do?

[dirty_escort]

i've seen it done before, not sure how though, i brought the white dials with the side view of the car cause i wasn't sure how hard it would be, think they have con nectors that just plug in

The tacho cable should be sitting behind the clocks, not in use.. Should be a straight swap..

Tacho isn't cable driven, its electronic.

It'll either work or it wont, mine doesn't but everything else does. I need to get round to wiring the fcuker in really, think its just a case of taking a feed wire from the ECU

I meant wire, no cable

Aha, Matt my friend - you have a 1.4 PTE too, do you not? Not that it should matter, as I think the wiring on all multipoint injection (mk6's at least) should be the same for this.

 

Wired mine in the other day straight from the ECU and works great - ignore everyone else's advice about feeding from the engine bay and listen to me, it's so much neater & quicker! :lol:

 

 

Just need to tap into the black/white wire leading out of the ECU (behind the passenger footwell coverplate) and feed that directly to the 'S' (signal) on the back of the tacho, or to the correct pin on the multiplug connector strip if you've already got a redundant wire there (mine was 5 up on the blue connector strip from memory, but no pin or wire there so went straight to tacho instead).

 

Note there are actually two wire bundles leading out of different holes on the bottom of the ECU mounting, one nearer the door and one further back into the footwell. Both have black/white wires too The one nearest the door isn't the one you want as typically that was the one I tried first, so unwrap some of the electrical tape from the furthest bundle from you and tap into that. I'd been putting off wiring it up for ages as I didn't want the hassle of running another wire through the bulkhead and then playing with coil pack outputs - but a glance at Haynes gave me the obvious solution

Nice one mate

 

I actually looked through the wiring diagrams last week, and came to the same conclusion

[dazzler24]

is the wiring the same for the mk5?

just got around to putting in speedo and rev counter works without the need for wiring cheers to everyone who replied.
