hooked up msd ok and runs fine.but have not hooked up tacho yet as just want to check and be sure.it says in the workshop manual that:
" the tacho is a pulse type which monitors the increase and decrease of DC current of the coil.the resulting pulse is converted by the transistor circuit of the tacho to register engine speed." Then it has big bold warning letters that: "the tacho is a negative earth type,if incorrectly connected,transistors and diodes will be damaged!".the wiring diagram shows that wire goes to neg. side of coil but also there is a wire for dizzy connected also as per original.I have put the dizzy wires to msd pick up plug and wired as per chrysler orange and black description in msd instructions so original tach wire remains disconnected.

CAN i connect the tacho straight to msd 6a box connector or do i need an adaptor? .I have already thought about an autometer tacho but as the car is for street driving i do not really want a big tacho hanging of my steering colum as it would attract to much attention if i was pulled over and the constabulary might think i have some kind of race car LOL!!!!.

If a diagram of circuitry would help can e-mail one no probs!. Many thanks again guys.

You did not mention who made the tachometer, so I would like to see the wiring diagram before I provide you with an answer on this one. Please email it to me and I would be glad to look it over for you.
