I did a search here for a 5.9 EFI Swap and what I saw did not answer what I wanted to know. I kept reading how much better it was to change to the EFI to a carb.

Here is what I need to know. What is involved in making the efi work in a 64 Valiant?

The Donor is a 96 Dodge Ram 1500 I can get everything I need to do the swap from the truck itself. So I know installing the engine is the easy part and there is a modification to the trans tunnel to fit the transmission.

What is needed to be done to wire up the computer and to have a running and driving car?

Please no post on how it will be easier to convert the EFI to carb.

Thanks
 
I subscribed to this thread as I am thinking the same way.

From what I understand, the 98 Ram has an all electronic transmission requiring the OEM computer to run it. You'd be better off with years 93-95 that has both the overdrive and lock up converter that can be wired up to work properly.

As for the fuel injection control, I think you'll be using aftermarket like megasquirt.
 
Cliff,when I first came here(Last June),someone took a poll on making a wiring harness work I. the earlya bodies.He had at least 40 or 50 posts on it.Great idea,your real problem ismaki g the trans fit.I have a od core,itstoo big for my 72.Your pre 67. trans tunnel is even smaller,requiring serious mods.

That will be the thing to kill this project.
 
I have thought of doing this same swap but i wanted to know if when making the tunnel larger does it affect the a/c / heater box.Or in most cases just the heater box?My thought was to make the trans tunnel a bolt in removable cover like land cruiser fj40's.
 
Maybe hook to a 904,Cliff.Mine was 99,notched the flexplate to fit my 727.I thought B&M made a flexplate for this swap.If not,check out Torqueflight Patti on Ebay.They sell weld on weights for flexplates.I will not cut the floorpan.
 
You can use the A500 trans if you just want overdrive.The front part of the trans tunnel is fine but you would have to widen the back where the crossmember is. I have a buddy who has been modifying Magnum harnesses to fit in any vehicle.He sells them on e-bay all the time.I was just talking with him about modifying the Ford computor and harness for my Dakota since it is more tuneable

if i was going to do it this is the way i would do it :coffee2:
 
Asa go back and read the first post. Only Posts on how to do this.
 
If you have the whole harness and computer out of the donor it should be cake. The PCM doesn't know what it's in so as long as you have everything (Key and ignition switch, obd2 connector, all sensors, and you could modify a 904 or a 727 bellhousing to accept the crank sensor if you can find a flexplate for the swap.)
 
Ok cliff im done man u have fun . i had to ask cuz that would help some one tell u how to do what u want done , forgive me for asking a ? im out
 
I'm subcribing to this thread, because if anyone has successfully adapted the factory EFI controller and wiring to work in an older vehicle, Im interested.
 
I swapped an older mopar to TBI fuel injection from carburated I know its completely different going to MPFI but heres what I suggest

go to your local dodge dealer with the year make model and VIN (if possible) and get a wiring diagram for the truck your using the harness from. what I found out is that if I had of got the bulkhead pin out for the truck I removed the harness from there is only a few power wires that go through the bulkhead that are needed, give them power and theres one ground and the engine should run sitting on the floor

Cliff,you might check out Megasquirt.A universal EFI kit that will adapt to any efi application you desire.You can order the ECM prebuilt,or save a couple of c notes.Order the diy kit(kinda like the old Heathkit stuff.Check out www.diyautotune.com.
 
ok i have done this its fairly easy. i had a 5.2 magnum from a 92 dakota in my lancer before i decided to do my new build. and i have also done the same with my 1958 dodge pick up. if you use any other automatic other than the a500 ora518 you will have to nitch the bell housing for the crank sensor such as the 904, 999 or 727. or even the a833. this is pretty self explanatory of the position when you mate the trans and engine together.

use the a body motor mounts or those from schuemacker. use a body oil pan with the appropriate magnum pan seals. you can use either the magnum exhaust manifolds. a body manifolds, or a body headers. now wiring is bascally three wires for fuel run and start you can simplify everything by doing away with the relay center from the magnum donor vehicle. just retain the pump relay and the asd.
hook up double dark blue wire of your a body to the blue wire of the asd relay and fuel pump relay. and wire from start terminal from ignition switch to other side of asd relay. to find this wire take a test light and locate at bulkhead connector when you turn key to start. it helps if you have a wiring schematic for both vehicles. here is the schematic i made for my 58 if you can follow each wire from the ignition switch on the diagram you can trace it to its destination on the magnum harness

How did you do the fuel pump? I will get diagrams for the donor truck. What is the ASD?
 
ASD means Automatic Shutdown Relay

The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.
