with that truck u HAVE to run ur power right off the battery. i did one a few weeks back...

Big Dog,

I just checked if the car has oem anti-grind, yes it has.I turn the key to start after the engine runs, and the starter didn't drag. What happened is that the illumination in my custer instrument and dash all went out when I turned the key. I don't know if that's normal. But the starter didn't grind.

After that one night, I left the r/s disconnected untill the next evening and reprogrammed the system. Everything works good so for. I like the tach, because it stops the starter as soon as it detects tach from the ignition coil. So, I will leave it untill it acts up again.

But why would you use voltage sense with factory oem anti-grind. And why 4 sec crank time. Doesn't that put wear on the starter?

Wy did the starter grind if the car has oem anti-grind and the r/s was set for tach. It wasn't that cold either that night. About 45º. Also I did not know for how long the r/s tried to start the engine. It took me maybe about 3 min before I got to the car and then it tried for another 2 times. Sound very weird to me.

Thanks for your reply.

Splaudio,

yes they ran the power right off the battery. At least the did something right.I don't know if you read all of this post.But I had this installed.Only thing I did myself was the tach wire, the hoodpin, wired the mud light (side mirror) and fog light to light when car is r/started

ok ur up and running now,good. i never checked for oem anti grind, never do. i didnt know that suv had it though...

Allright, my tach never work well. It had been buggy since it was connected.

I used the white wire at the ignition coil. Worked fine for a couple of days and then it started to act up.I have to tach learn the system like every two days. Then it won't recognize the tach again. And sometimes the starter grinds cuz it doesn't read any tach.I think i will switch to voltage sense.My question is. Can I leave the wire and use the white wire at the ignition coil. Or do I have to connect to a constant 12V.I know that the tach at the ignition coil is AC and it reads about 3V.But when I switch my meter to DC the same tach reads 14 Volts. So what current is the ignition coil and can I use that for voltage sensing.

Thanks in advance

if you have problem w/ finding or using tach-sense, then just use volt-sense and its corrective crank timing. gl and post your result.Houston,TX

Profuse007, thanx for ur quick response.

The tach-wire is run and connected. But the r/s doesn't  read the tach-sense that well.I want to do voltage-sense. My question is:Do I have to rewire the tachwire or can I leave it connected to the ignition coil?

Thanx
