Ok, I've searched this forum high and low to no avail.

Here's the deal, The '00 EX has an 8pin single harness and the '95 SiRII Dizzy has 2 plugs (one 7pin, one 2pin). The EX harness fits into the 7pin plug on the dizzy and I routed the one Blk/Yellow wire from the EX harness to the 2pin SiRII harness. However, I can't figure out what the Dark Blue wire comming from the SiRII 2pin plug is for and there isn't a left over wire to hook it up to. I looked at a '99 SI Dizzy plug and it looks like this wire is a delete. I'm stumped. Please help. BTW I have all the other wires matched up as per a schematic that I was given. I don't have the $ to buy an OBD2 SI dizzy and I already have the OBD2b to OBD1 jumper. Thanks in advance for your help.

Wiring OBD1 (in order left to right, top to bottom 7-pin plug off dizzy)
1. Yellow/Green
2. Blue/Green
3. Orange/Blue
4. Orange
5. Factory Delete (no wire)
6. Blue/Yellow
7. White/Blue
8. White

2pin plug
1. Dark Blue (what does this go to? This is where I'm lost)
2. Black/Yellow

Wiring OBD2 (in order L to R, T to B 8-pin plug off main harness)
1. Yellow/Green
2. Dark Blue
3. Green
4. Yellow
5. Black/Yellow (cut and spliced to Black/Yellow from 2-pin plug)
6. White
7. Red
8. Black

All numbers match on OBD1 and OBD2 harnesses (except 2-pin). Hope that helps

bump for help please

 

The dark blue wire is the tach signal. The 99-00 Si does not need it, as the cluster gets its tach signal directly from the ecu.
