ok so i put a carb on my 88 now the tack does not work i am using msd 6al i just need to know if i can keep my tack. and what wires i can remove from the efi harrness. and now my temp and gas gauge does not work. thanks .

 

just looked at the fuses thay look good.

 

Just because the fuses looks good doesn't mean they are. You have to test for continuity to be sure.

 

what is driving the trailing coil???

 

i am runing msd just with 4 coil packs. I do not know how else to do it

 

did the continuity on the fuse thay are fine what is next

 

How do you drive one MSD 6AL into 4 coil packs???

BTW, the MSD 6AL should have a tach output - just connect this straight to your stock tach wire.

where is the tach wire for ste stock tach

 

exactly the same thing I was wondering... How would you even get the split???

 

Check the Mazda FSM for the wiring diagram, or maybe some of the FC electrical gurus *cough*HAILERS*cough* might chime in?

Tach wire is yellow/blue at the trailing coil...

I'm wondering how this person is running an MSD box with 4 seperate coils and managing to deal with trailing timing and split?!?

 

i dont know i just split the wires

 

so all the 3 coils are firing at the same time??? You don't have dedicated CDI systems for each coil???

That would be- (how do I say this politically correct....) less than optimum.

 

then how do i do it. all coils firing at the same time

 

YOU
CAN'T

then help me get my car on the road please.

 

Switch to a '81-'85 distributor setup, or put the stock (or an aftermarket) EFI system back on.

 

we have 85 dizzy but how do we hook up igniters to 1rst gen dizzy on second gen

 

Check the 1st gen forum and search for "transistor trick".

Have you considered looking at the wiring diagram for the 2nd and 1st gen?
