I resently changed my car over, all you need is the peddle and the throttle body. And a ecu that will run it.

Mine was in a classic shell so had to make a bracket to mount the peddle yours might fit direct?

Note the linearisation on the duel peddle and throttle positions are not he same ( each sensor needs setting up seperatly )

Exactly what mike said above.
Regards mounting the pedal. Don't bother with these conversion brackets etc that you see. Just weld a platform in to mount the pedal to. That's how I did mine

Was that something you bought of the shelf or did your mapper make the loom
up for you?

Like Mikes, mine was on a mini loom that went straight back to the syvecs. From memory I think I got the plug from Tim at JT. It was a friend of mine who then did the pin outs to the exi

If your are on motec, I'm guessing Dave Rowe is doing your mapping?

Tim at JT supplied my mini loom but I ended up swapping to a Syvecs S8 and modified it myself and made my own wiring kit for the new ECU

Correct me if I'm wrong but a dbw throttle body won't fit onto a cable inlet manifold so a later inlet manifold is needed. I'm going to be doing this very thing and got all the bits from Matty b and plan on running it with a simtek.

Hmmm yes and no.
I run version v3/4 mechanical heads with a dbw throttle. I had to convert the inlet manifold flange to accept the dbw throttle.

i believe the later heads can use a manifold that uses dbw throttle from the factory. This just bolts together
