I have an HSW harris speed works Air to fuel, timing module. But sadly no diagram or start point for it.
I was told its plug and play, but there some type of 4 point relay i need to be connected to, according to the person who sold it to me.
Can someone please help me Figure it out, and let me know where the 4point relay is.

I tried doing a search, but it seems like HSW is no longer in business.

Thx

 

I have the interface on my cts-v and there is no relay....plugs inline with the mass airflow

 

Aside from the MAF plugs, there is 3 additional wires. A blue, black, and white. Where do those go to? or are they needed? I'll try to upload a pic of them.

 

Here is a picture of the HSW module.

 

Anyone?...

 

Bump...

 

this is one of the few diagrams I made for someone with the Interface.



Blue...power
Black...ground
White...tach

Please let me know if you need any more help.

 

Man! Thank you so much, now i can begin to move foward...

Blue...power
From what i see, i can wire it up to my arm switch and be good.

Black...ground
Any source of ground, right?

White...tach
Do i have to get into the dash? what wire em i looking at to hook up to?

 

You only need the tach if your using the top end fueling feature...right from the instructions with mine "white wire for tach is optional. If not used then the top end fueling feature is still useable, but will be based off airflow and not rpm. Connect BLUE wire to triggering device(window switch, tos/wot switch etc...connect BROWN wire to the ground on the relay that controls the solenoids. For LS1 applications the GRAY wire needs to be spliced into the tan wire on IAT sensor..." Hope tgat helps

 

On a side note....it says specifically not to hook up power to the arming switch

 

if you still have the instruction manual...any way you can scan it and post it?

Lots of folks still have the unit would be nice to have an online reference to the instructions

 

Ill try and get it scanned when I get home from work

 

I started a thread with pics of my HSW interface instructions that I scanned...pics are kinda small but I couldnt get them to upload any other way. Heres the thread...
