What Year TCU Can I Use To Replace Mine?

[rico05]

I have a 91 S13 copue, and I have reason to belive that my timing control unit is out (dash lights intermittent, wipers sloppy, etc) I do have a HUD as well. DO I need a TCU from a car that also has a HUD? What year TCU can I use? Thanks in advance!

kind of off topic but not really. where is the tcu? is it the little box above the ECU or the one inside the middle center console?

It is the little white box next to the fuse block next to the driver's dead pedal. It is behind the black panel. ABout 5"x5" in size. It controls many of the interior lights and power accessories.
