Typo in the title. My OBD@ plug had a bad connector pin at #16. The flasher went dark when I plugged it in. Now the green/red at #16 has no power. Where does it get power? What fuse? Where to read on SN95 OBD2 pinout or diagrams and protocol? Thanks. Any help will be appreciated.

(BTW. My sig pic is old. Now 3V heads, 2.8 Mammoth @ 28psi, etc. 9.88/137. Better coming)

Assuming the wiring from a 99-04 MY applies, check fuse F2.31 in the CJB.

Next measure the resistance from DLC pin #4 (wire color BK) and DLC pin #5 (BK/YE) back to battery negative. Post. Should be low.

If the resistance is not less than say 2 Ohms, check ground G104 and G204.

wmburns, thanks. You saved me on some issue a couple of years ago. I'll check these.
