chris mk3 320 Posted January 3 (edited) Can anyone help? I'm a dummy when it comes to the sparks, here is what I've got to work with, going into Cortina rev counter clocks Edited January 3 by chris mk3 Quote Share this post Link to post Share on other sites
John Mack 327 Posted January 3 It takes it's pick up from the negative side of the coil, at the clocks it may be possible to figure it out following the "trace" on the circuit board........judging by pic I'm thinking this is on MK3 facelift or MK4/5 ?

chris mk3 320 Posted January 3 (edited) Yes mate MK3 Facelift , I've added lights on the board, so I know the two inner connections must be for the rev counter, that's all I know Edited January 3 by chris mk3 Quote Share this post Link to post Share on other sites
John Mack 327 Posted January 3 I take it you're adding a rev counter dash to a car that previously just had speedo/temp/fuel gauges ? I remember doing this to my Crusader about 20 years ago , comparing the rear of the 2 dash clock sets will help, the wire colours are possibly NOT in the same positions on the multi-plug. Hopefully Craig will have the definitive answer !? Quote Share this post Link to post Share on other sites
chris mk3 320 Posted January 3 Yes mate exactly, Craig has given me a bit of guidance, but not exactly sure where to move the plugs on the connector Quote Share this post Link to post Share on other sites
