V1 Type ra 4 pin TPS conversion to V3 3 pin
 

Currently finishing off a manifold conversion on a Version 1 Type RA to the later front entry manifold off a Version 3.

The original Throttle position sensor is a 4 pin connector & the newer version 3 is a 3 pin connector.

I understand that the brown wire is to be dis-guarded as its not used, But has anyone out there thats done this conversion Know the sequence that the orginal V1 loom wires fit this later style V3 TPS.. Ive got red black & white But unsure of the order they fit.
Currently showing error 31 TPS sensor. and the cars shuts down after a brief running period.

Any assistance would be great as I have no wiring diagram for the earlier loom.

Vehicle is fitted with an esl at the moment pending fitting a simtek/alkatec on tuesday
Cheers in advance

I could be wrong, But the Brown wire is not required on the 3 pin plug........This is going from memory...I read something about it somewhere!!
Question on the IACV is it the same plug or wiring?
Thanks
Dan

From what I've read and a previous thread I had. Brown wasn't used.

Iacv plug is the same. Goes straight on.

Oh **** sorry....Skim read fail!! Think its the opposite way of the V1 and V2 Plug
