84 533i electrical problems
so i recently just dicovered that my car is missing a bunch of it connectors and wiring from the harness because the previous owners before me had put in a after market alarm system. didnt like it and decided they didnt want it so they took it out. Well now all but two gauges work on my cluster. The speedometer and Tach do not work. but the fuel gauge, temp and lighting all work. Should i try and get a new wiring harness and do it myself so i know from a base start on where the wiring works. and if so will some one please point me in the right direction because ive had no luck on finding one anywhere where i live. it super frustrating.
