Custom Wiring Harness
I just wanted to share this because I haven't seen this before in a Z31, although I'm sure it's been done.
I am fortunate enough to have access to an auto-electrician who formerly made wiring harnesses for Australian Touring cars. So I basically emptied all of my bank accounts and had him create this for me - overall I'm pretty happy with the results so no more broken connectors or short wiring for me! Also no more Christmas… -

Sorry to hear about your Christmas
I do a fair amount of custom wiring harness fabrication here at work and that looks like a quality job.
The tooling for properly crimping the terminals is prohibitively expensive for the common shadetree.
Which is why i recycle and solder mine where i can.
Would like to see some photos once you get it installed.

She's all in the car bro already and wired up to a Haltec stand alone ECU. It's super tidy in the engine bay, I'll get more pictures once it's back from dyno!Originally posted by Z_Karma View PostSorry to hear about your Christmas
