Yea I found that but it doesn't explain what color goes to what from the KA to the SR between the two clips well if it does it confuses me alot.

Can you sum up which colors and functions go to the grey clip and which colors go to the brown clip?

Seriously? did you look at the chart?

The Chart "Sums up the colors" and the functions

I understand it's simple but without them infront of me its hard to see how to wire the two clips with the descriptions, I ran out of daylight to finish it.

The chart does not differentiate which plug which wire belongs to. Cut your two SR plugs off the SR harness. Cut the similar KA plugs off the KA harness. Put the KA plugs /w a workable amount of wire up to the SR harness. Match up the colors according to the chart. Solder wires. Tape/shrink wrap.

Is that it? please correct me if im wrong.

Ya I just went out and cut the end off now and have the KA clips and the SR clips in my hands trying to follow the chart. I'll give it a shot.

Just throw those SR Plugs to the side. Basically replacing the SR plugs with the KA plugs

Very nice pics. ok discard the SR plugs. Now compare the KA plugs to the SR harness where you cut the SR plugs off. You will connect the KA plugs to the SR harness

PS. Looks like you cut the KA plug wires a bit short. May be a b1tch.

I am pretty sure that some of the plug wire will need to be mixed. For example a wire off the KA brown plug may go where the SR grey plug was cut off.

Are you serious? Of course the wires are different colors between KA and SR THAT'S WHAT THE CHART IS FOR.

Sell your car.

Got me where, what do you mean what does it run?

What do you mean you didn't do the first harness?

Start matching the colors, not all of them get used. B/R and BL/R BOTH go to the B/R on the KA plug. Match what's there and tape off the leftovers...

look man just follow the chart i was looking at those plugs and some of the wires match. i think theres like 4 to 5 wires that don't do anything. just dont expect that lets say the sr brown plug and the ka brown plug all the wires match up because some of the wires you'll need will be in the place on the gray plug. i dont know if that makes sense but if you see the wires match the same on the ka then most likely there right! what ever doesnt match doesnt get used.

Ya I appreciate it I finished it last night then crashed out, I was just confused a to why you mix the clips up but its all wired up, taped up and about to put them back on the main harness. Thanks to all that tried to help and weren't giving me a hard time. Hopefully she'll fire up no problem today.

Congrats! It was pretty exciting when mine started first try after I did my harness using that how-to on FRsport.
