good evening all, ive just had my instrument cluster sent off and had digital gauges fitted, fuel, temp, rpm and speed.

the speedo is now gps
have to run a water temp sensor into the engine
im struggling to find the signal wires for the fuel and tachometer

i have a 2003 impreza turbo, it used to be a gx but previous owner did an engine swap, has an ej20 in it now, ive been told its an sti ecu, dont know if true or not, but can anyone help me with some wiring diagrams, or any other advice to get this all working please? i must state i took the old cluster out to replace an led and when i put it back the speed and rpm didnt work, i thought i broke them hence me getting new digital gauges so im not sure if there is a fuse maybe for the tacho aswell.

any help is very much appreciated

 

Hopefully the attached might help..........
