Yes. Helps prevent frying things by accident. :)

And also, it works exactly like how dawm just said above. The point he was trying to make is that when you use the MSD 8689 switch, you are using the switch to CLOSE the butterflies in that window you want them closed, because with that switch you only have one "on" and one "off" point. You don't have two "on" points. So you can't set it to come "on" from 0-3200 @ WOT and then come "on" again from 5000-redline @ WOT. I hope this makes sense cause I don't think I can explain it any better. :lol:

How did u make your lower CIA tube from the mag manifold to your AEM or iceman. Did you just buy a mag intake, or just make the lower tube???

I bought Louie's old magnum Ice-Man short pipe. So I have an Ice-Man/AEM intake. :lol:

erm i dont really understand but i guess I'll have to just do it and try to figure things out on my own. I went to my local autozone and they didnt have any single pole double throw relays. I have to find one quick.

just a quick question. MY dad and I were looking at the setup today, and he wanted to know if there is going to be some sort of gasket where the accuator sits??? Thanks in advance

no but there should be. my motor got all rusted but kevo took care of me and cleaned it all out.

could you tell me which lines are designated to which numbers on the relay? I just got my harlan rpm switch in. :D

i was gonna use some sort of sealer when i put it on...last question from me about this....does anyone know the angle of the CIA tube from the intake manifold to the throttle body. Autozone sells differnt elbows and i wanted to make sure i get the right now. Have a couple of differnt options 25, 30,35, and 45 degree bends...

well i finally finished mine today.. figuired out how to solder good too =P even integrated the LED i wanted to tell me when they are open. altho since the relays and wot/rpm switches are inside i can always hear the 2nd click of the relay..

problem is i cant get the zex to read WOT properly.. i got it to set to 94.7% so i tried again and it went back down to the 15%.. cant get it any higher then 15% and im following the directions to the letter.. rather annoying. i dont know if maybe the SAFC2 is pulling more throttle information and the zex isnt getting enough to read.. i dunno its just voltage..

and i tapped into the wrong wire to control the mtv .. needed to tap the brown/white.. brown/yellow which is the hot wire to the MTV didnt seem to fire it off. so brown/white is the pcm signal to the relay in the PDC. then ill have technically 3 relays, and fused power for the MTV.

welp for some unknown reason when i put the AFX PCM back in to see if i could get it to idle, everything worked just fine.. cept my LED which burnt out.. (its a 12V LED.. with the diode and whatnot.. no idea why it died) got the WOT switch set to about 97%.. closest i can get.. either its 97~ or 15~.. oh and the af/x pcm with working butterfly.. oh my god :) it just keeps revving.. i peaked at 7250rpm (ran out of clear road) according to my safc2

Have a couple of questions about this...

1. What wire do i tap into on the TPS sensor? There are 3 wires there, which one do i pick?

2. For the Window switch (MSD). Do i use the Grey of Yellow wire as the ground?

*****Edit

Ok i went back out to see what i did. I think i messed up the TPS sensor wire (i hooked it up to the orange with a purple stripe) and MSD yellow or grey wire ( i used the yellow wire). Any help would be appreciated

Lastly on the MSD switch what should be on and off

Right now i have
ON: 3.2
OFF .5
is that correct??
and i have it on 2 cylinder mode

I know this is a revival of a dead post... BUT

is the a Zex TPS/WOT switch absolutely neccesary or can you make the setup just work with just a harlan window switch and the relays?

if I would have to guess I would say thats about a 10 degree turn but I'm probably wrong.

Well I have a magnum intake, harlan rpm, zex tps, and 100 ft of 14 awg wire on the way...all I need is the relays and I should be good to go. I'll take some pictures along the way and let you know how it goes. The only thing I'm worried about is my sxt intake...I might just use the crappy stock rubber bellows for the time being if I have to.

using the stock bellows should be fine, no one has documented gains from using a solid/straight piece of pipe over the rubber accordian tube

Anyone with the harlan switch know which wire goes where (color wise..I'm probably just too stupid to figure it out) and how to program the lower range? I couldn't see it in the directions anywhere. Hopefully I will do this on Saturday.


edit: Well I re-read the directions for everything today and I got the wire colors figured out..they didn't seem like some foreign language this time haha. But I am still not sure about the harlan programming..I know how to set it to turn on at 3200 but how do I program it to turn off at 5000?

the stock setup works like this

0 to 3200 AT WOT = ON
3200 to 4900 AT WOT = OFF
4900 to revlimit AT WOT = ON

with the msd switch i had it setup like this which gave me the Idle-3200/WOT as well as 4900/WOT:

always on (always suppling ground)
at 3200 turn off (taking away ground)
at 4900 turn on (suppling ground again)

im not sure if the harlan is setup like the msd, because the msd came with 2 signal wires, one that always supplied ground until the unit said not to, and one that didnt supply ground until the unit said to. and since the msd cant be configured to turn on at TWO points, i used the one that always supplied, and used the WINDOW on the msd to turn OFF (3200-4900) the manifold rather then turn on.

hopefully this helps ya a bit, considering what you described you were doing is incorrect (it turns off at 3200 not on)

-- sorry for the late reply.. i dnt venture around the forums much these days

wouldnt you need a window switch and an RPM switch to get this thing to act just like an R/T because the secondaries open twice, at high rpm and low if you were going with harlan

Well if you used a normally closed relay, you could just use the harlam to open it between 3200 and 5000.
