sohc-dohc + sohc hud

[phrozen]

ive read plenty on this swap. so no flaming =P and yes i read the spring break swap.

Heres the situation, have a 89 coupe with a 95ka and a nightmare harness that some retard b4 me did. half s13 sohc part s13 dohc and some fuckin plugs from a s14. Im thinking that i shold try to get a full s13 dohc harness or sohc harness. and redo the engine harness. But i have a sohc HUD. My friend has a 89 coupe with 95ka with sohc hud pretty much exactly the same as what im trying to piece back together since dude b4 me fucked shit up. I guess my question is can i use sohc harness and ecu with 95 ka? i dont know how my friend has the tach from the sohc hud working if hes running either a s13 dohc ecu and harness or s14 harness and ecu. I would take a look at my friends car but he works like 50 horus a week and has a wife so its kinda hard to take a look at it
