Anyone have an idea how I go about removing the wires/pins from OBDI A,B,D plugs?
I know the plug "opens" but I cant get the wire out...any ideas?

Thanks

With Scissors....j/k try cutting around the pin if you don't want to save the adaptor.

Figured it out! You have to stick a paper clip into the plugs and push on a small clip.

Good old paper clip

B18C-EJ1

Hey HX guy, I tried that, and it didn't work for me. Were you able to do more than just the one?

OBD1?

What you doing with an OBD1 wiring harness? Some sort of conversion?

HX_Guy

Yes Im making a OBDII to OBDI conversion harness.

The paper cip trick worked...got about 11 pins out.

I have made a list of what each OBDII pinout equals which OBDI pinout
OBDII Connector D

1 TPS = D11
2 ECT = D13
3 MAP = D17
4 VCC1 = D19
5 BKSW = D2
7 PHO2S = D14
8 IAT = D15
10 VCC2 = D20
11 SG2 = D22
12 SG1 = D21
13 SHO2/SG = NA
14 SHO2S = NA
16 EL = D10

OBDII Connector C

1 CKFP = NA
2 CKPP = B15
3 TDCP = B13
4 CYPP = B11
5 ACS = B5
6 STS = B9
7 SCS = D4
8 K-LINE =
10 VBU = D1
11 CKFM = NA
12 CKPM = B16
13 TDCM = B14
14 CYPM = B12
16 PSP SW = B8
7 ALTF = D9
18 VSS = B10

OBDII Connector A

1 INJ4 = A2
2 INJ3 = A5
3 INJ2 = A3
4 INJ1 = A1
5 SO2S HTC = NA
6 PO2S HTC = A6
9 LG1 = A26
10 PG1 = A23
11 IGP1 = A25
12 IACV = A9
15 PCS = A20
16 FLR = A7
17 ACC = A15
18 MIL = A13
19 ALTC = A16
20 ICM = A21
22 LG2 = B2
23 PG2 = A24
24 IGP2 = B1
27 FANC = A12

The only one I dont have a mathc for is OBDII C8.
It stands for "K-LINE" and "sends and receives scan tool signal.
Is this teh same pinout as OBDI D7 "TCD/RXD"? OBDI D7 is the only pinout I have left unaccounted for on the OBDI diagram. OBDI D7 wire goes to the "Data Link Connector"

K-line and DLC is the same. They just call it different on OBD-II cars.

In order to remove the pins with the paper clip, you need to pull back the pin holder on the back of the plug. It locks the pins in place. HXGuy forgot to mention that.
