i took out my NA motor and NA harness and dropped in TII with correct harness.....but now i have problem.......on my TII harness there is no white plug which goes back to alternator. I can`t find it at driver side of harness (on same part of harness where is CAS connector). Basically it was on passenger side of harness on NA and its not there on TII harness.....i need to know where i should hook up those two wires to be able finish it....

ANybody knows ?

thanks

Well, I know it is on the EFI harness(passenger side harness). It should be connected to the front rotor injector plugs.

That's one of the problems doing the TII swap in an early NA - the voltage regulator wire on the NA is on the ECU harness, and on the TII it's on the driver's side harness.

You can probably get around that - get out the shop manual and trace the wiring.

And here's one that will bake your noodle - you can use the NA ECU harness with minor modifications...

i traced and fixed

black/white wire and white/black wire...one goes to Main relay, other goes to CPU inside of car....works ;o)

here we are, couple days later :

car is running, pulling really hard, seeing 10psi on Defi boost gauge (no fuel upgrades yet, my walbro pump is in NYC ))

hoses are connected this way:

everything blocked off, no BAC, EGR, ACV, OMP...simply nothing...

installed aftermarket BOV, air vented

vac hoses follow :

lower intake manifold, lower one goes to fuel pressure regulator (stock one)

lower intake manifold, upper one goes to stock boost sensor and to BOV

upper intake manifold, only one which will stay not blocked after turning space backwards goes to boost gauge (Defi)

TB mod done, tb ported

problems :

hesitation - not 3800 but much lower, car hesitate down from 1000-1200 whats idle now.....its idling rough....but once it will gets air or fuel, it goes really fast to redline, thanks to lightened flywheel ;o)

anybody got tips what to look for hesitation ?

i haven`t checked timing yet, will try another MAF, probably another injectors too....

could be problem with FPR hooked to lower intake manifold nozzle ?

i will put another exhaust manifold with EGT probe later this week, downpipe ordered at rx7store, hopefully it will be here before christmas.....

vacuum leak, recheck your timing too

timing is ok, changed air flow meter and its seems to be better now, still kind of hesitation, but it could be because of all stuff removed, otherwise car is pulling really hard, just hitting fuel cut too much.....i`m not going to hook up FCD, i will order Haltech and drop it in with my 1500's which i have ready for secondaries and walbro fuel pump....

k2rd radiator is on its way as well, hopefully stuff from rx7store will be soon too....

other problem we noticed is noise in higher rpm, matezz is kinda afraid that flywheel is unblanced or so....
