alright to make a long story short here i go:

have an 87 fc n/a. did an engine swap with a 91 jdm turbo.

everything is working great except for a couple tiny things.

turn signals and hazards (and the high beams as well).

i know now that its rediculously a pain in the @$$ to convert from s4 to s5 had i known this i may not have but what's done is done...

so i really really need to know if anyone has successfully fixed this problem and how they did so. whether there's some rewiring that can be done or really anything.

please please please guys. i know someone out there has to have been able to gotten through or around this problem.

thanks everyone!

 

Well, you're going to start with every bit of rewiring you already did to pull of this swap. Did you swap in a S5 instrument cluster, or adapt the S4 to work? Either way, this is where you should be looking.

Download the S4 & S5 wiring diagrams and track down all of the wires related to the hazards, turn signals and high beams. You're in for some more rewiring fun.

 

yes sir, s5 instrument cluster has been installed. oh and as well fuel gauge isn't working...
