I'm thinking of using butt splices into the ecu loom....does this sound like a good scheme?

Always solder IMO.

 

[Nismo Dave]

Cool cool, i'll do that then

 

[james]

yes, always solder, especially when your ECU is involved

Ok, i got it all wired in and it works in speed mode but the revs mode is giving some strange readings, the only reason i can think of for this is that i've wired it up to the wrong pin, i wired it to the pin marked in the manual as "tachometer", should i have wired it to one of the 4 pulse wires for the ignition coils??
