Rev 3 install question

Ok so upgraded my rev 2.5 to rev3 with harness and everything. Everything is connected but one thing. The PWM meth kit came with an small (relay, "small black power box") and when I got the rev 3 it also came with one on which power wires are connecting to it by female blades. I now have 2 of those little boxes do I leave them like that or do I get rid of one??
Kinda confuse, I hope I was clear enough.

That's likely the 2step/nls relay... Check out the install instructions for it

Yes, you can just ignore one of the relays. You only need one when you are running the Procede/PWM Meth combo

Shiv, there seems to be a lot of confusion on this. So you wire up the PWM relay and that will work for NLS as well?

Nope. For NLS, you will need a 2nd relay. The first relay i was referring to was just for the PWM meth/power power (so it draws power from the battery and not DME fuel/ignition circuit)

On Monday, I'm going to whip up a little schematic for those who want to use NLS but are running rev3 proceeds with rev2 harnesses.

Ok so I have 1 relay from pwm meth kit with 2 female terminal (PWM meth kit wires) then I have 1 more relay with procede Rev3 female terminals.

The older Rev2.5 had 2 terminal going to 1 relay but since I no longer have 2.5 do I leave those spots empty??

I think you are thinking it is more complicate than it is. For your Procede and PWM meth kit, you will only be using one relay. And you will install it exactly as shown in the PWM meth install guide. The install is the same regardless of Procede revision.

The only time you will add another relay is if you use NLS/2-step and the NLS install guide describes this. I'll add some clarity to it on Monday when i get back to the office.

Ok cool. Haven drove the car in 2 weeks so in kinda have the urge to drive it tmrw.
Which one do I remove. The one from the PWM kit with to wires connected or the one that came on the procede?

Just look at the install guides and it should be pretty clear. If you don't want nls, discard the relay that is new.

Ok. But the PWM power wire is different on rev3.
Before on rev2 u would cut the power wire (red wire in middle) add the female blades then instal them on the corresponding terminals of the relay.
On rev3 the relay if full practically so I just leave it as it is but my question is do u need to cut the red power wire again just like on the rev2 then install the female blade on the PWM relay?

Yes, rev3 installs exactly the same way when used with a pwm meth kit. Cut power wire that goes to green connector, crimp on blade connectors and route to relay. As shown in instructions.

That would be helpful. Correct me if I understand this wrong. The butt connector installed in step 3 of the NLS instructions (same step both harnesses) is deleted, and female terminals are installed. Then the proceed side of the wire goes into terminal 87 on the PWM relay, and the power wire coming from the NLS relay goes into terminal 85 of the PWM relay.

yes sir. the red wire coming from the procede goes into terminal 87 on the pwm relay and the other red wire coming from the powerwire connected on the NLS relay goes on terminal 85.
