efi on 260z

[Linton]

OK I have read posts and tried to glean out the answer but I haven't found it yet ,,I have got the 280z efi manifold computer and wire harness, I have spoken to my local auto electrician,, who I have absolutely zero confidence in, he told me it would be a massive job to get it working, and wasn't worth it... Previous owner of the parts told me it just needs a 12v wire to make it work, so exactly how hard is it, and briefly with some details how do I go about the electrical connections.

Thanks in advance

thanks Benny

just trying to find out about it at this stage we only have one auto elec in the town so I will have to do it my self if I go ahead with it. just about got it on the road if I can get some s/h seals and stuff off the guys (see wtb) it will help enormously

The EFI harness is basically a self-contained system. From memory, you only need to interface a handful of wires into it to get it going;

coolant gauge

ignition power

tacho output

start signal (not sure if this is needed)

fuel pump output (low current - used to switch pump relay)

 

These are all present in a connector that is normally mounted mid firewall.

that book would have been handy way back when! i just basicly fluked mine in because the wireing diagrams sucked that i got

that wire that goes to the coil is near the plug for the ecu i think well i had that to a switch for power then theres like 1 more to the ignition switch and the earth the rest is for the motor i dident have to do the guages stuff it ran with out it but it was easy too

i remember when the wrecker told me as i was a youngen that i would stuggle with all those wires i couldent afford the motor and box at the same time so i took the motor first and came back a few weeks later to get the box hes like how are ya going with the conversion i said how ya think i got here go look out the front haha

make sure you do that to the sparky when you get her going!

as for being not worth it thats crap it was great not having to reset the carbys ever again or points it was down on power but still went good enuff i only got greedy and wanted to turbo it thats where i stuffed it up trying to get ems dialed into the dizzy and the intake manifold was leaking like a sieve

i can tell you the rb harness is 20 times harder to figure out

jet tronics is basicly lego in comparsion

If you really want I to work, draw a diagram and send it to me or post up here online.

I've wired up 4 r30 L24e in the last 3 years, and 1 280zx, plus another l20et

 

It's not the best system in the world, but for daily duties it's nice and stable!
