hi folks
the check engine light came on today on my 94 wrx while on the way for a mot, checked the codes and it came up with the speed sensor. it now also only boosts up to 8 psi,(is this normal?). the problem is i cant find it on my gearbox, ive looked on my uk wagon and can see it but its not the same on the wrx, any help would be grateful
thanks

 

forgot to mention that there is no wiring or plug for it to go into either, would it be on the back of the speedo clocks as ive changed those
thanks

 

bttt anybody??????????
