Have 94 ranger w/ 2003 bed

[94 lngbd]

The bed came with the taillights also ,but they are a 2 bulb set up & my 94 taillights are a 3 bulb set up. Will the 2003 taillight harness plug into the 94 chassis wiring where the taillight harness connects?

If so i'll be going to the bone yard to get the taillight harness.
Or could the newer wiring be spliced in?

my 99 had 3 bulb system and i converted it to 2 bulb, u can use the connectore under the rear bumper to get the signals, or use a trailer connector
