1989 Chevy silverado

I made my own on my '77 (later welded them on):

Cousin Eddie: DId you ever have issues with pinion angle after a flip?

In reply to SkinnyG (Forum Supporter) :

No sir. I almost always use Belltech parts and they include a 1 inch spacer to put between the trans and trans mount. Smooth and vibration free with the spacer.

Ok.

I did end up running a 1" spacer at the trans, but have been having no end of issues.  I cannot find the happy vibration-free spot, and truly never have.  Two different axles, and two different driveshafts even....

I'm just that lucky.

Anyone have a pinout for the pink wires? 

I removed them all from the fuse box and labeled as I pulled. 

But I haven't found a chart thsg actually says what each wire is (03 burb)

i can probably get you a wiring diagram for the suburban if that's helpful

Sure,  if it's not too much trouble.  

Thanks

whats your email?

I forgot about this but i sent the diagram today.

Not a bad view tonight.

I have to merge the stock harness and the 5.3 harness still. Once I pull out all the junk from the stock one I'll make sure everything works. Then I'll pull it all back out and make it purdy. 

Been working on this when I have time,  such isn't much often.  

Getting close. Intake is on,  fuel lines are hooked up, relays and fuses added.  

Cranks over by the key now,  all the factory stuff seems to still be working after cleaning up the stock harness. 

Fuel pump primes when I turn the key,  I'm using the 89 + coil wire (has power when cranking)  as my trigger wire for the main relay. 

No spark though.  I'm wondering if I got the transmission nss/gear position switch wrong.  

We had the vats turned off earlier.  Knock sensor and transmission harness and vss are all plugged in.  

I don't have the cruise control wires hooked up yet.  The brake switch isn't hooked up yet either , i have to look and see what else. 

I had power at the white coil pack connector but no spark. I can smell from the injectors,  so it's getting fuel .

I really like the look of these, I'll gave to pick one up so I can have an even dozen projects going on around here.

Getting closer.  Looked it over this morning in the light.  Found a ground wire that I didn't have hooked up. 

Now I have a working throttlebody (dbw). Still no spark, going start searching now.  I'm going double check power and grounds at the coils. 

It's alive

Stuck on linkage. 

I've seen people used the factory rods and modified them to fit. 

But I just can't figure out how that will work with the 4l60e nss and the exhaust routing, the drivers cat is probably in the way.  

I saw a mention of a guy saying to use a astro cable but I can't find anything on that. 

I'm watching closely what you decide to do as I'm doing basically the same project right now.

One thing I have going for me is that my transmission guy knew I was doing a swap into an early truck and when he built my trans he swapped the shift shaft for an earlier one so the linkage requires no mods. 

I haven't gotten to the point of running exhaust yet but I know it's going to be a bit of a challenge.

Probably lots of cutting and welding. 

I had no plans to start with.  Just fixing each problem as it arises. Lol

Got everything working.  Dakota dash in was running and driving and then...

Running out of ideas.

This is on the 89 chevy with a 03 burb donor.

Won't shift into 3/4 and no speedometer.

Checked resistance on the vss wires from the plug to the ecm. Both good

Thought I messed the tac up so I swapped in another one. The only change was that it threw a code (p0502).

This all started when I was trying to get the cruise to work. I did it like the attached pic, after I hooked up the blue wire is when things became messed up.

It threw the transmission in limp mode and wouldn't shift into 3/4 and threw a high idle code.

I unhooked the wires and cleared the codes. But that didn't fix anything

I tried an oriellys vss thinking that was the problem. Speedometer doesn't read, with the old vss or the new oriellys one.

I'm Running adigital Dakota dash using the bus to get readings. All other gauges work besides speedometer and I verified that speedometer is set to the bus setting.

Dash shows all the gears when moving the shifter. Park, reverse, neutral, o/d, drive, 2, 1

Then I tried running the dash with the speed sensor instead. Using pin out 50 I set the Dakota dash sensor to use to the sensor instead of the bim. Still no readings.

Tried auto cal mode in the dash to see and it didn't read any pulses.

Didnt have any of these issues before i tried hooking up the cruise.

Other thing I just noticed is when shifting through the gears the Dakota dash says park when in neutral. I don't remember it doing that before

Did I somehow fry the ecm? I'm out of ideas

No speed signal even when using a live stream. Popping up a p0502 now

Fried the ecm. Got another one back up and working now.  Almost time to go back to my buddy's place.  

Just have to bleed the brakes and adjust the shifter linkage.  

Trucks out of my place and back at juans.  

Any one else have a short driveshaft after doing a 4/6 drop?  

Not sure how I didn't notice that but when we had it up on the lift when the exhaust was getting built I noticed it was short.  

Is there a longer yoke to make life easier?
