You got it. And for your first question, the driver side plug has wiring that goes to back up light, fan relay, and ecu wiring. Wiring for the gauges is on the passenger side shock tower plug. If you get stuck n need help, feel free to ask. Im making my 6th or so DPFI to B16a conversion harness as we speak. I posted up progress pics of the current harness on my FB page:

Ok cool So long story short extend the tps 6 inches and eacv 8 inches? yes or no

Then c1 n c2 moves over to b10 n b12? yes or no

Then put wires in c1 n c2 at ecu, to the round dizzy plug I added where the old square dpfi dizzy plug was right?
yes or no?

i dont understand what i have to do with A1 A3 A5 A7 & A15 all i know is they are for the injectors
( to make it a little clearer ill post a picture of my harness when i get home from work)

You are going to run a wire from injector 2 and 4 (count #1 as closest to timing belt) to ecu plug a. Injector #2 will go to A3 and injector #4 will go to A7

Those green/white wires all need to be connected like they were before. Those are the grounds for the following sensors:
IAT
ECT, and
TPS

Reconnect them, I would solder them and heat shrink them.

For c1 + c2 what should i use the same color blue/green & blue/yellow or do i go to the local store and buy some wire and if so what gage? im thinking when i go back to the junk yard i can attempt to de-pin it at the ecu (on mpfi honda) and see if it comes out pulling it so i could atleast have the length and the same color. what are the ideas?
i appreciate the patience.

It's not honestly going to matter as long as you an remember which wire is which. It will be hard to find oem colored wire. So here is my suggestion:
For blue/yellow use plain yellow
For blue/green use green

These are colors that are more commonly found at any parts store so it will be easy enough to distinguish.
