Wiring needs to be close in years. There is more emissions equipment on the 93-94. I tried to use a 91 harness and it was definitely different from the 93 harness that I got to use.
I've also come to find that the wiring and ECUs in the 93+ Rangers is very different than it is in the Explorer. As far as an ECU is concerned you need to stick with the same year as there were quite a few changes year to year. I do believe I mailed off my 91 harness to someone on here but I'll take a quick look around tonight.
Also make sure to have your clutch switch plugged in. With a manual harness you'll need that switch to be working in order to start. You can try to jump the solenoid to see if it is a starter interlock issue or an ECU issue.
You need to jump the pink to the red/light blue at the NSS plug from the original automatic. Since it is in series, the clutch pedal safety interlock switch will still function.
You can also connect the purple/orange and the black/pink of the NSS to the reverse light switch of the manual transmission to get the backup lights working.
