Default OBD0 to OBD1 conversion help!!!!!

http://www.-------------/install/OBD0-OBD1.htm
Double check all connectors and start it up. You will need to re-pin the OBD1 distributor to match the (88-91) OBD0 plug as well. This step is fairly easy. Just match all the colors up. There should be 2 white wires that are on the OBD0 distributor plug and only one on the OBD1/2 plug and an extra yellow/green. The larger of the two white wires on the OBD0 side needs to go to the yellow/green wire on the Obd1 side. Therefore, the smaller white wire on the OBD0 side needs to go to the white wire on the OBD1 side. Basically you want to have 2 of the like plugs, either male and female OBD0 or OBD1. You can also cut and solder on the new plugs.
the two white wires look the same to me

one white wire runs with all the other wires of the dizzy.... the other runs back into the conduit.. seprete from the other wires.. i ASSume the seprete wire is the larger one but to me they both look the same

tracing the wiring back through the harness.. one of the white wires doesnt go with the others..




says the thicker white wire is for icm.. would it make sense for that wire to run seprete from the others?



does that mean the thicker white wire is the one that runs alone

umm...i doubt it... well yeah, but not those two. i know that there are two white ones. one is kinda off white, the other is white. over the years they look the same. i get them mixed up all the time, did it on my first swap and 3-4 after that lol... never had one that was fucked up from it... one way (wrong way) it will crank over like its got a bag ignitor/no spark, the other way...well it will start if the rest of your ---- isnt fucked up...

disclaimer: your a dumbass for listening to me if you ---- your ---- up

ok bear with me now..

first the unmolested wiring diagram which i will only link to..
http://i32.tinypic.com/2s9t0l3.jpg

then the wiring diagram i drew over.. pointing out the 6 wires which are together with the white wire.. and the other white wire which goes alone which is connected to the icm.. therefore i came to the conclusion that the white wire which goes alone into the harness is the thicker one since it goes to the icm.. therefore that white wire will be connected to the yellow wire on the obd1 side.. and the thinner white wire which goes in with the other wires will be connected to the other white wire on the obd1 side.. make sense?
