Greddy Turbotimer - Speedsignal

[Zonder]

Hi guys,

i have installed the Greddy Turbotimer, but i don't know where i can gat the speedsignal. (Somewhere from the speedo ?!)
I place the wire from the TT to the speedo and don't know with wich wire i have to connect it on the speedo.

Need your Help.
Thanks

I think your best bet is to find a copy of the ECU pin out diagram and find the speed signal wire and tap off of that. I dont suggest you cut the wire and rejoin it. I think it best to strip back the plastic sheathing, and solder the turbo timer speed signal wire to the ECU speed signal cable. I could be wrong, but this is how i would do it.

That's what I did, took it from the ECU. I can't remember where I found the pin out diagram from, but it was probably on here somewhere.

But maybe i want to connect the SLD from HKS to the ECU later and i don't wont to ruin it.

I've found some pics in the service manual from this forum and i think that i should take the pin nr. 14 for the speedsignal, but in an other forum some guys say to me that i should take the pin nr. 31
