Neutral safety switch is something other toyota forums have mentioned might cure this. You can look into Tundra forums as they have similar issues.

Just got the notification for this thread. I got the power straight from the battery with an inline fuse.

So here's something to ease these diagram and wirings: Going by the 2 terminals A and B of the fuse, and 4 terminals of the relay as per the attached diagram (fusebox1), this is what they correspond to: A: Gets constant power , +12V : connect this to new relay pin 87 B: Gets constant power but...

Yes, once the p1600 code is fixed thanks again to your advice. :)

Jumping a cable from battery positive terminal to the f terminal of where the factory relay sits. As per the pics in tnt original thread fix post.

Didn you try to jump a canle connection directly from the battery. Does that still work ?

I figured I'd someone else stumbles upon other posts they would get the solution too. Thanks again. You're awesome !

thanks, perhaps for the clarification of others who read this thread, is it correct to point out that the E terminal where the original relay was connected and is left out in the pictures here for the solution (ofcourse corrected in your updated kit); E terminal is connected to the BATT node of...

thanks much, what is a good place to tap into the constant 12V, what about the to your kit that's feeding the relay, can we simply tap into the same source and feed terminal E. In essense, I assume what we are doing is shorting terminals B and E with a fuse in between, or getting a constant feed...

Thanks, thanks. as for the P1600 code, someone mentioned that you sent them an update wire etc to fix it. i'm guessing based upon the link you posted for the error code that somehow you have supplied node E which is left blank with a constant 12v source ? if so , where did you tap into for the...

adding another diagram, showing that the BATT terminal of the ECM requires 12V as well. given in the bypass harness we are leaving terminal E blank, that leaves BATT of ECU needing the 12V that it doesn't hence throwing a P1600 code for me and a few others. Waiting for someone who used the...

Hi Bob, did you ever figure out the error you used to get when you were powering the bypass kit straight from the battery ? i'm getting the same error and like you said, the error goes away when i put the original relay back in. interesting thing is that i don't put in the EFI fuse back in...

DrJMan, did you leave the terminal E blank ? if so did you ever get the P1600 code by leaving it blank or did you feed it power ? thanks.

I have the same scenario with the kit throwing the P1600 code. what is the second part of the kit you received ? is it getting power to terminal E from a different source ? if so where is it getting the power from if you would kindly share. thanks much ! :)

posting a picture of how power should be applied to factory relay. based upon the kit by medtro, your kit terminal E left out of your kit, as per the ECM diagram I'm attaching that needs a constant battery power which if it's not there is likely throwing the P1600 code for some. I still...
