Ignition/Wiring harness for my 2.4 Bridgeport EFI

[15 Mustang]

I have a 1986 Mercury Bridgeport 2.4 EFI motor...it has an 8 pin "cannon-style" wiring harness...I purchased a Marpac #7-1150 push-to-choke ignition switch which replaces Mercury #87-88107 and #87-88107A5 switches it has the following diagram for wiring hook-up on the back of the package/switch: A=accessory (4-pos switch only) B=battery C=Choke (electric) I=ignition M=magneto and S=start.

My wiring harness has red wire which I have connected to B=battery on the switch, yellow w/red stripe connected to S=start, purple wire which I have connected to I=ignition, which leaves (2) wires left.....solid black and a yellow w/black stripe....ANYONE KNOW WHAT/WHERE THOSE LAST (2) WIRES HOOK-UP TO ON THE BACK OF MY SWITCH???? Confused.....15 Mustang

Solid black should be a ground
Yellow with black stripe is your fuel enrichener ( choke )

Thanks for your reply...I aware of what the wires are for..... my question is where do they hook-up on the back of the ignition switch I've described in my posting

Anyone on here know what color wires off of my stock Merc wiring harness attach to the MarPac or SeaSense ignition switches??? (See my original posting for switch layout)...thanks in advance

you should have antother yellow wire with a red tracer down in the harness.... usually it is tapped up... unroll the tape and you will find another yellow with a red tracer..... hook it up to the yellow with the black tracer, this will choke the motor when you push the key in!!!!!!!!!!
just make sure black is grounded...
