Hi All,

im trying to find the electronic speedo cable as im installing Satellite nav in my car. I done a search but only came up with the speed cutout cable... does anyone know which wire is hooked up to the speedo?

Thanks

ya tellin me!? thats why i couldnt be stuffed looking for it :eek:

OR does the speedo read a signal from the gearbox? is it a mechanical system or does it have a wire that i can splice and attach my satellite nav system to? if its done by wire, where can i access this wire and what colour is it?

Thanks

you should be able to locate the speed wire going into the ecu.

kuro, i think the wire that you may be talking about is "wire 53" which is the speed cut/HICAS diagnostics wire. This doesnt send the pulse to the speedo to give it a speed reading. looking at the ECU diagram it doesnt reffer to any speedo wire, just a speed cut out wire which makes think that the wire is attached to the gearbox? if its is, i wanna know how to access it from inside the cabin and what wire is the "signal"wire or (+)

im not sure about that... but when i installed my timer i had to splice into the speed wire going inot the ecu, and this shows the km/h reading on the timer. so i thought it might help you.

[borry]

really? can you by any chance tell me which wire you spliced?

dude,

try www.apexi-usa.com or the hks usa website to download pdf's of wiring diagrams. i used the apexi safc and other related diagrams becuase they have they show the wires like rpm and speed necessary for those spiffy turbo timers.

good thinking, thanks. Ill check out their wire diagams
