i just bought a 1991 240sx coupe that has a S1 Rb25det, i've got the engine wiring down, I think.

My major questions is can I get the 240sx lights(head/tail, break and reverse lights) to work if i am on a haltech ECU controlling the Rb25? are the lights even affected by a new engine?

I've spent some serious time looking for how to make the s13 tach and speedo work with the rb25 and I haven't found anything. it you could refer me to some threads that would solve my issues or can explain it to me that would be much appreciated.

Thanks - Holden
