How to replace the stock ignitor & coil with MSD 6A & AEM EMS. Mr2celica sw20 st205 st204

This is for 91-93 Toyota MR2's (SW20)
This theory could be applied to similar vehicles such as 93-99 celicas.

I wrote this about a year ago on MR2oc.com to help the members remove the stock ignitor and coil and replace them with an MSD 6A unit. This can only be done if you have an aftermarket ecu, such as AEM EMS. So here it is, I hope this help anyone who find it.

Just like the diagram states, you need to move the jumper inside the AEM unit. It's JPC1, it has three pins in a row with a jumper that jumps two of the three pins together.
The jumper can only be set 2 ways, so just set it the opposite way from they way it was when you opened the unit up. To get into the unit you need to take out a small allen head screw that locks the board in place, just make sure you put it back in after your done and don't loose it because it is quite small. I suggest soldering and shrink wrapping every connection.

If you have any questions leave me a comment on here.

Tanner Foust's "Scion tC"

Is it awesome? Hell yeah. Is it a scion tc? Hell no.
I bet on the scion message boards theres fanboys going OMG that scion tc is so cool! I'm gunna build one!
Yeah.... right. I like how it's RWD and built with Toyota's V8 Nascar engine, but labeling it a scion tc is just wrong.
It's practically a tube frame chassis drag car with a fiberglass body. Labeling aside this car is mint though, Huge kudos to the builders and fabricators who made this beast.

Oh and I found this gem as a comment here.
"anyone that says "S13", "S14", "S15", "AE86", or "R32" will be asked to leave because cars have names and only douchebag ricers refer to cars by production codes."
I think he's just sad because he doesn't know what any of those letters and numbers mean. :D
