can someone tell me which terminals to bridge to make the rev counter work with wasted spark pls.
ive done a search and the pics ive seen seem to be of a different rev counter to mine.

This is how I did mine. I know its a 4x4 one but may help.


There is a picture on the MSD instructions isn't there IIRC.

Yeah it's a different board to yours,i don't have the fitting instructions if someone can post them up I'd be grateful
Thanks for the pic.

Mine just worked without any change required, not sure why

kosienutter

Yeah if your car has a very good loom then they can work without the modification.
Unfortunately when I did this mod it dropped my voltage on my SECS monitor by half a volt as you obviously by the looks of it, it needs more current to the rev counter doing the bridge of the wire. Might be wrong.
If no-one can post a picture of the instructions I'll dig mine out when I am home next Sunday for ya bud.

Thanks for that mate,I'll fire a message over to stu in the mean time,really don't want to put another rev counter in there.

Have looked at the instructions and it says not applicable to 3dr Cosworth's and early Sapphires. Sorry not much help in the end, but it says there is a number for Speedy Cables in Swansea 01639 732213 which might help??

I got hold of the instructions and I'm picking up a set of clocks tonight in an attempt to install the later rev counter but retain the boost gauge.
gonna be a pain to do but will be worth it if it works.

Cool. Hope it works.
