Need some help to plug Holley pro jection

[Chriss]

Hello

for trail driving I found a used Holley pro jection. It looks pretty good and have only 3000mls run.
It's the TBI. My engine is the 360 V8 with Edelbrock Performer cam and manifold.
The JEEP have no more the canister and no air intake.
Now I don't know how to plug the vacuum lines to the injection.
To plug the PCV is clear. Also the spark port. But what's about with the EGR? Where is this port at the manifold and which is the best place to plug the manifold vacuum to the injection? I believe the shortest way is the best. Right?
If I have no more the canister I can close this plug on the injection?
Many many small hoses and with every hose a question.
I'm happy if somebody could help.
Chriss

Chriss,
You need to edit your profile IE year, model, engine year etc..
Also send us some pictures of your engine, hoses, manifold & projection, for us to help you.

Wie geht es dir?

There are serveral differs Projection units.

If you go to the Holley website you download the right manual.

I love my 1D on my AMC 258 i6 / 4.2l .

Since you say you have an Edelbrock intake you might not have the EGR, if you do it is on the back of the intake. If you do not have it plug the port on the TBI. You should have at minimum the spark advance for the distributer and PCV on the top of the intake tube. definitely posts some pics and ask us any question you have we will try to help best we can

thanks for your answers. Now here are a few pics where you can see the vacuum ports at the intake and at the injection. The worn 600 carb is still on place.
In the back you can see my lovely CJ.

Forgot something important. I still have the stock distributor with the ignition computer. I won't buy an MSD or Mallory cause too expensive for me. Here they want 1200$ for the distributor and the ignition module.
The stock ignition things I have are Ford duraspark? I'm not sure..

Well you do not have have EGR on the intake, the hose coming out of the back of the intake is your PCV so that will need to be plugged into the TBI, you also have vacuum advance from your distributor that will need to be plugged into the TBI. The Holley set up comes with a MAP sensor that needs to be plugged in the TBI item #14 in the manual. you have a CTO switch on the front of the intake that I would not bother to hook up since you have no other real emissions equipment on it. Also the hose on the top of the intake tube goes into your air cleaner unless you have the aftermarket one, then you can leave the hose off completely should be nice. I am not sure if the Holley TBI set up controls the spark or not but the Ford ignition set up is just fine and can be converted to an efi controlled distributor any ways connect the above hoses and plug what you do not need

73CJ linked Holley's website for the parts, this is the link for their instruction manual in pdf https://ac17cb7e3cc3506f0d23-7386af....ssl.cf1.rackcdn.com/techlibrary_r10179-1.pdf

Thanks for help I have the manual of Holley's TBI. To put the vacuum hoses to the TBI is no problem. I can see it at their pictures.
My Problem is the intake manifold with its many plugs and which plug is the best.
The second problem is the circuit at my original ignition modul. Which wire must I cut and which not. This is not clear at the manual.
Did I need special diameters for the vacuum lines??

 

[Chriss]

I take a look at the manual. I have a temperatur sensor, the throttle body, the throttle body sensor, the fast idle solenoid and the electronic control unit. Also fuel pump and fuel filter.
Thats all. I don't have Holley's 950 dominator.

Chriss, I'm thinking your ignition module rewire is probably whats known as the "Nutter Bypass" This removes the computer controls from the carb fuel mixture and distributor advance. Since the fuel mixture will be controlled by the new computer and the distributor will use its mechanical and vacuum advance. There are a few write-ups on the "Nutter Bypass" on the net, possibly you will find a comparison and find it explained easier:

[Chriss]

Thanks, but I don`t have the computer. I don´t have a electronic controlled carb. Only my worn Holley 600. I think the "Nutter bypass" is done, cause I missing the computer. My CJ is 1983 and had the AMC 258 i6 / 4.2l . Now the 360 V8.
What I mean is the ignition module. Must this pluged by stock or must I cut something? At the manual from Holley I don´t understand:

FORD DURASPARK SYSTEMS
On vehicles with this type of ignition system, a power relay must be used. Connect the end of the fuseholder cable to terminal 87 of the relay. Connect terminal 86 to the RED wire on ignition module.

What did they mean with RED cable at the module? Must I cut this?

 

[Torxhead]

The red wire on the ignition module is what supplies power to it from the ignition switch. Whatever that relay is powering needs power when the ignition switch is turned on.

 

[Chriss]

This is the picture from the manual which show the relay.
I looked yet at my ignition box. There are two plugs. One with two wires coloured white and red and the second plug with 4 wires coloured orange, violet,green, and black.
Now if I understand it right is the red wire on the 2 wire plug that I need.
It cames from the wiring harness and is coloured red/white. Than goes to the 2 wire plug and from there coloured red wire to the ignition box.
I understand this: I must unplug the red wire from the ignition box. The red/white wire from the harness goes to terminal 86 on the relay and the red wire from ignition box goes to terminal 87 on the relay.
I hope I've been right. If not please tell me what I do wrong. I'll wait for your
answer.

That pic you sent really helps, I think. It provides another source of voltage to the module if you are not getting the required 8.5 volts to it. So if your oem wiring has a weak spot like in the ignition switch and looses voltage, that relay addition will make sure the module is getting enough voltage. Got it?

 

[Chriss]

No. The TBI isn' t mounted yet. First I wanna know and understand the manual from Holley.
I read a lot about that the Holley TBI sucks. Other say it's fine if absolutely correct mounted and tuned. I'll do it right that my CJ can drive.
If I have all the good and helpful informations I mount the TBI.
And since I write my questions a lot of good informations comes from you

The red Coil + Ignition to Holley relay #86 - do not splice distributor wires. I say again do not splice distributor wires, always go to where they terminate, usually a ring connector. You have got it right just no splicing.

If you look at your factory wiring diagram for the CJ your red/white tracer wire comes from the ignition switch through the fire wall in terminal 13. It is the main power wire, it powers your ignition both the coil and ECU and it also powers the alternator It is already spliced several times by the factory. So Holley wants you to power their computer from the factory ignition circuit. The way they are showing is their computer will get full battery voltage thru the relay. The relay is activated by the ignition system, so when you turn your ignition key "ON" that red wire powers your ignition system and then will close the contact in the relay for the Holley computer.

I have an 83 CJ7 it also had the "feed back computer" on it. I ditched it as it is completely useless. I did it the hard way by looking at the 1982 and earlier wiring harness to figure out why my ignition wasnt working with out it.(I didnt know about the nutter bypass til later) So yours is already done no need to worry about it

Good morning guys. YES that make sense. Now it's clear. I think the discription at Holleys manual is not 100% clear (or I'm stupid enough to understand it )
I'll test it next weekend with my other JEEP guys. Hope it will run. Must buy some new fuel return lines. My are too small.
If it won't run, I'll look for the truck avenger. But first I'll test the injection.
Have a nice weekend
