Okay. So I have sat down and gone through my wiring harness diagrams and seperated everything out by circuit and these are my questions:

1: I have found several areas on each diagram (3.0 and 3.4) with the +B symbol- ECM, MAF Sensor and o2 sensors to name a few. I am guessing that the only one I need to worry about is the one from the ECM. Is this correct?

2: Looking at my breakdown of each engines circuits, it looks like I am going to have to match several wires from the 97 3.4 to only one wire on the 95 3.0 and vise versa to get the system to work right. Am I reading it right or is it a one to one match on the wires. I know that the starter wire has to be spiced into two others. Just want to make sure I'm understanding this.

3: Since my 4runner no longer has ABS, ADD, Cruise Control and the auto t-case, do I still need to wire in those circuits or can I just cover the end of the wires and leave them be.

Thanks

1. There is one in the body harness that you will need to worry about, i drew you a diagram awhile back.. That is how you go about the +B business.

2. I know on mine i had to put two into one, i don't remember doing that to the stater though, i had one B-W from the body harness plug and i ran my own wire from that to the starter.

3. Technically you don't have to hook them anywhere but make sure you take care of them so they do not mess stuff up later, like touch and fry things.

Thanks Sam. Now if I connect IH1 pin 6 (L) from the 3.0 ECU (FP) to IH1 pin 23(G-Y) "EFI COR" to II3 pin 26 (G-Y) EFI COR to ECU (FC) will that cover any fuel issues. IH1 is from the 95 3.0 and II3 is from the 97 3.4.

Or do I need to do the Bosch relay no matter what. BTW I have looked thoroughly through both schematics and I can't find and FP+ that was mentioned in an earlier thread, just the FP mentioned above.

Thanks

The "to fuel pump" should go to the large blue wire that is coming out the stock 3.0 COR that is above your glove box. Cut that and run it to the relay as shown.

A few more things I am unsure of:

While looking at my wiring breakdowns, I noticed that I have two wires from DLC1(95)-TC and TS, and 3 wires from DLC3(97)-SG,SDL and CG, that I can't figure out how to connect them. SG and CG are grounds. SDL appears to be liked to both o2 sensors, both knock sensors and the cam and crankshaft position sensors. I guessing that I need these wired into place. Where do I need to connect SDL and SG? Both of those are part of the II3 plug. Is there any way to plug them into the 95 DLC1. I don't see those terms listed in DLC1. Thanks



After further perusing of the wiring diagrams, I noticed that all of those wires are ground out to either the left or right intake manifolds, however the above sensors are still in play with SDL. If I don't find a way to connect these wires, am I gonna have problems with the above mentioned sensors?

Also on the 3.0 there is a large black/yellow wire(IH1-15) from ecu position STA spliced to the COR from the EFI relay and also to the park/neutral switch. I know its important but cannot figure out what it will connect to on the 3.4... any help is appreciated.
