Awesome!!! Thanks for the write-up!

No Problem hope it helps some one out !

for the dash plug, you state the blu/blk wire goes to the blu/blk on the rb harness, when I compare that color wire to the one on the ecu pinout http://www.scribd.com/doc/17587822/rb25detpinout it says the blu/blk is for the o2 making the ylw/blu the engine temp sensor. Is this a mistake with the diagram I'm looking at or is it just a color mix up on the write-up? Thanks

Don't rely soley on the color of the wires. If your reading the pin out right and yellow blue is the wire you see go with that one. From what I understand there where variations in wire colors. I'm not being a d*ck, I stated that some where in the write up. Just for future refrence if anyone else looks it up haha good luck !

Heeeeey! I got a S13 with a RB25det.Just swapped my old HUD dash and the window into the it.The whole HUD gauge cluster werked perfectly before I took it out to swap into my new 240. Speedo from the old dash werked before but was waaay off.tach was off to but that's an easy fix. Looking for threads on wiring the HUD up.As of now everything werks on the cluster.Just the HUD speedo is not werking after I swapped it in.Any Ideas. Wrote down ur pin pics and all so I can go thru it and see where I'm off. But if u got any ideas why the HUD isn't werkin since I swapped it let me know dude! Thanx !!!!!
