so I have a 93 b13 with a gti-r swap I just got the thing done and I can get it start or even turn the d*m ecu on or the fuel pump so im just about ready to stick a stock usdm b13 harness in there and call it a day ,currently im running the gti-r ecu and harness but something is not jiving , so are all 91 - 94 engine harnesses the same ? I did this exact swap about 5 years ago but I have been out of hte game for a while so help a brother out khttp://i146.photobucket.com/albums/r262/RBNMYZ/PICT0053.jpg

93and94 harness is not the same

nice cold side piping where u get it from

so mine is a 93 with the electric speedo so so what years are interchangable
thanks 4 the props on the Z that is my claim 2 faim 87 300zx rb25det I think I was the first to be stupid or dedicated enoughf to start and finish this swap in the usa

I do all my own piping

there are more pics in the members ride section I just posted them today

oh yea 94 is a lowport so if you have a 93 and want your speedo to work get a 93 harness

how much to make that same cold side pipe let me know

well it would be kinda hard to do with out your car here and not knowing what I/C you are using .http://i146.photobucket.com/albums/r262/RBNMYZ/PICT0037.jpg

there is a few more pics of it

so back to my reason for this post , I assume the nx2k or a se-r would be the same correct

This might sound retarted, but did you ground the harness?

it is grounded out the arse I checked all the grounds on the ecu and all are good
pin 4 (ecu relay) has 12 v ,pin 38 (ecu pwr source)has .66 v ,pin 46 (ecu main power sorce from fuse block) has 12 v ,pin 47 (ecu pwr sorce) has .66 v , pin 109 (ecu power sorce from fuse block) has 12 v ,but no lights on the ecu , no fuel pump ,no power to the coil .but my apexi avcr ,neo safc, ITC, all power up when I turn the key and power down when I turn the key off . I tried this with 3 ecu 2 of which were gti-r ecu's one a usdm b13 sr ecu . I would love to have the b13 wiring diagram so I could trace out a few wires that I think are the culpret. mainley the large plug just above the trannie . I have a gtir pin out and wiring diagram .

can someone give me a hand here

hey arent you blowing off metered air...did you check all your fuses and relays under the dash and under the hood

it is a recirc I just didnt have the hose on in that pic , I checked every fuse ,fusable link the engineinside and out , has 2- 4 gauge grounds one from each side of the block to the frame and grounded from the trunk mount batt to the frame and from pass side strut tower 2 from the VC to the frame . and the car will turn over all day long im just not turning on the ecu ,fuel pump , ign system

what distributor or you using? what ecu are you using?

here you go
