wiring a MSD 6-al into a KA (external coil type)?

[fiznat]

Anyone done this before? On the back of the MSD box there is a diagram that shows a line for battery +, battery -, 2 wires for the coil, and wires for a "magnetic pickup" on the dristribuitor or something. On the factory coil there were something like 3 plugs that connected to it with about 8 wires in total of different colors.... anyone know how all this goes together?

LOL, c-mon college boy...you can be the test pig.

[fiznat]

lol nevermind, got it figured out! Ill post pics later.

[WDRacing]

Dude, do a write up, take pics of what wires etc....I know quite a few guys interested in this info. Myself included.

[Shanglin]

YES !!! please please please coz I have one too and "thought" I had it hooked up right not sure but I think it messed up my ignitor chip. Thanks duuude

[fiznat]

lol well it was pretty easy, the wires are just funky cause they re cross and double over with that weird "resistor/condensor" thingiemabob.

I wont know for sure if its 100% right until I start the car (wont be for a few more weeks), but I'll get pics and post about it tomorrow (too tired now).

Basically though:

Thick Red: Battery + Thich Black: Battery -, groundOrange: Coil +Black: Coil -White: Black/Red Stripe on coil harnessThin Black: Lime Green/Black Stripe on coil harness

I'm pretty sure that's just about it. I'll double check and get pics tomorrow.

ooh NICE link!

So much wiresToo confusing!!Damn

Could anybody PLEASE post the correct wire combinationI will be wiring a BTM, does the wire combination is the same?For a 93 external coil, stock coilThKS

[fiznat]

There arent that many wires, but yes I will help since this is my original post and I am re-doing it anyways heh since my box was bad (ebay...)

Thick red and black are the battery positive and negative. Obviously you should have +12v on the red one, and a good ground on the other one.

White wire is the trigger wire. This connects to the green/black stripe wire that can be found in your coil harness.

The thin red wire needs a switched +12v that is only on when the ignition is on. This can also be found in the coil harness-- the wire you want is black with a red stripe.

Orange and thin black are the coil wires. They go to the positive and negative (orange +, black -) on the coil.

The magnetic pickup thing on the other side of the box is not used.

Its really not that bad of a setup at all. I'm sure the BTM is very similar since it must receive the same type of power wires and will need the trigger wire and coil wires as well. There is probably (although I'm not sure) just an additional port for a vaccum source.

If you have any problems feel free to ask!

JWT has a great write up on it. You think doing it on a s13 is tough--tyr an s14 where you have to convert to external trigger first---what fun that was.

yeah the S14 jobber looks like a beyotch. If I had to do that I think I would just get a S13 distrib and do it that way.

[WDRacing]

Definitly...I'm switching to a S13 one of these days myself.

[Projex240]

sucks cuz you have to swicth the euc and harness out too. If you already have a jwt ecu or something, your screwed. I did my distributor, it was all that bad actually. I have one here id sell to someone if they wanted to buy it already converted to external triiger for msd.

[Structure240sx]

wiring into an s14 isnt that hard u just burn your fingers a little.

using an s13 distributor would be nice so you can upgrade the external coil

[nissanfanatic]

The BTM is really easy. Its just cutting the negative coil wire and running orange to the coil- and white to the coil- harness. Then you just tap the coil+wire with the red wire from the BTM. Then obviously you have ground. Super easy.

Let us know how well that 6al works out. I'm considering getting one.
