Sorry I made a double post. I tried to edit and it appeared to delete my comment, when I made another post it reappeared.

Will a TWR make up for my mistake?

 

Here is a link to the 1992 electrical diagram pdf

idk about the other stuff, I lucked out and got 3 of the 4 shop manuals for my car out of the trunk of an XJS in a junkyard years earlier (guess which one I need the most). I know some of the facelift cars have CD manuals, but I am not sure which year it picks up. I have downloaded a free version before and there was no info for my 88, I would be pretty irritated if I have actually bought the software to find that out later.

 

Thanks again Sidescrollin! This document has everything I need to do this job... except for someone smarter than I am to do the job.

 

Fuel Injection loom for seq. inject with adapters for current ECM using both 6 and 8 pin wiring.

I have a distributor less plan too...
you will love it...

 

im not sure if I am getting you right , but you mention sequential injector firing

the current ECM will not provide you with this function , there is no way it can , as there are only four circuits that fire , each firing three injectors at a time

so all you have done with the wiring is run more wires than required that all have to be joined up back by the connector ?

unless you have a different plan?

You are sooo... right... the current ECM will not ever provide seq. inject firing

but I have downloaded the manual for a new ECM that I will be buying in the future... it provides for 12 seq. injector and tuning each cylinder it al so supports 2 three coil packs for a distributorless ignition system.. the coil packs I have picked out are SWEET... supports Knock sensors also... (do not know where the best placement for them would be though... it can be run with out them)
this is the coil pack... should help clean up the V
one for each side... (from a I-6 with the same firing order)

love being a systems engineer...

the way I drew it, I can use it NOW and then when I buy the coil packs and NEW ECM... I will not have to redo the loom I can just un plug it from the current ECM discard the adapters and plug it into the new ECM....

Right now I am fighting pin hole leak in the radiator... order new radiator bushings and found a place in the next state that will fix Mr. radiator
so I am fixing her and planning to up grade her to remove points of failure... (the ing system seams to be one )
upgrading to seq injection I am hoping to be able to tune her for better performance and fuel mileage.

these things will take a few years... planning for them now will help in the future to make the transition smoother and less work...

 

ah , i get it now

future proofing the loom

nicely explained to

BB

 

I plan to post all upgrades on the site just in case any one else wishes to follow that path...

Dyno is around the corner from me and is $100 for 3 pulls...
I will be able to get pre and post results... for $200

 

That looks like a coil pack from a Jeep Cherokee. Have you verified the physical fit on the v12 even if you saw off what i presume to be the knock sensors?

Has anybody here done a coil on plug for a HE V12?

I've seen some coil-near-plug conversions

 

Yes, it is the coil pack from a 4.0 Jeep I6 no knock sensors though...
shoot...
the 4 are mounting holes and the 6 are the plug connectors to the spark plugs...
and I do not care that it is not the correct size because I will just mount it nicely down one bank and make little sparkplug wires from it to the plugs... (times 2 one for each bank...)
It will still be a cleaner install and less prone to failure...
the ECM I plan to buy supports 2 3 coil packs for a V12 but they are so clunky and end up with the same junky looking sparkplug wires running all over like a distributor ....
I just thought this could end up looking a lot nicer...
