Ok been reading the forum/wiki for ages and Im still a bit lost. My van is an 86 with a scooby EJ25. I popped in a complete later dash today in the hope that the wiring would be all in place and the rev counter would respond, then I could do the resistor mod to get the correct reading. Unfortunately nothin

This is an diagram of scooby wirng loom (wiring was done before I purchased the engine) I got with the engine

An image of my dash connector

which seems to link up to this image with green being the rev counter

any ideas when I need to go from here, looks like the blue (rev counter wire) in the loom image is connected, tried connecting it to the green wire on the dash plug and connecting it to the clockset again but still nothing
any help much appreciated
cheers
