1980 rx7 DLIDFIS(gm igniters) install with pics.

[warwickben]

hey guys i figured id help you all out who have a 1980 rx7 or 1980 dizzy and want to convert to DLIDFIS. my buddy helped me out last night and i worked the kinks out to get it right.

we used this for most of the wiring setup.


now the steps. this is for a 1980 sa with the igniter's mounted on the strut tower with the fuse block.(fuse able links)

1st
remove the battery cable (-)

2nd
then remove the wires on the coils and remove them.
remove the coil mounting bracket thats still in the car, your going to re use this.

3rd
now follow the wires coming out of the bottom of the igniter box.
it should end with 2 plugs. one has 6 inputs and 1 has 2. once you discounted
those remove the fuse able links box from the igniter bracket, and let it dangle. then remove the igniter bracket and keep it for down the road just say you want to go back. then you can attach the fuseable link box on the side of the strut tower with one of the stock bolts.
i replaced the wire type links with plastic box typ. this pic shows where i mounted it in a stock hole. its hard to tell in the photo because of the light but the fuse box thing with the links is dead center.


thats the end of what you should have to remove.
you'll be left with 2 black/white wires(keyed power wires from the battery) and one yellowish one which is the tach. and 2 plugs that the igniter box plugged in to.

now for the wiring job.
the bigger plug your left with is where you'll run the green and red wires to the igniters. this is the pic from the fsm.

this pic messed me and my buddy up and cause us real problems which ill get in to. you can use that to know which tabs to use for leading and which to use for trailing.
you can see in this pic i swapped red for green/green for red. this fix the problems i had. if you read my other thread you will know why i did this.


from this point you would wire as the first pic says to. only thing we did different is we wired one of the black/white keyed power wires to the coils on the + side and the other black/white wires to all the b's on the igniters. and the yellow tack wire to the trailing coil - side.

how i mounted my coils.

i cut a plate of aluminum in the shape of a rotor, and cut 3 holes in it to drop the coils in. next i trace the hole patter on a paper to make a template and cut another plate. i can't describe the shape of this plate but the pic will explain. i drilled a hole in both plates, in the center of the 3 coils.
next i bent a a 1.5 x 1/8 x 6 or so inches in the shape of a L. i used the stock igniter bracket to mark the holes in the L shape bracket to mount to the strut tower. then i welded a gusset in the 90 bend to make it stiffer. this bracket holds the rotor shape coil bracket up.the hole i drilled in the center of the rotor shape plates act as the hold down and mounts to the L bracket. it makes it look like the coils and rotor shape bracket are floating. in the pic you can see part of the l shape bracket.


now for the igniters mounting. i removed the stock coil bracket(lower one thats bolted to the car. i laid it on top of the aluminum plate i had and put a center punch thru the bolt hole the was used to tighten the coils down. then i drilled that hole. then all the holes for the igniters.

and this is what i got.



list of parts i had to buy.
1 extra coil
3 gm igniters.
wire and quick connects.
1 bolt to mount the coil holder to the L shape bracket.
and some scrap metal i took from the scarp bin from work.
