The one you linked is the later 2005 up with a 2 wire outlet. I have one on my truck If you need me to snap you a picture of it and the plug. The one they are commenting on came in the Tahoe and Suburban around 2003-2004. Its the same alternator but has a different rectifier and has a 4 wire outlet in the rear. typically only 1 or 2 wires are used any way depending on the factory configuration. Not sure how it would effect what your trying to accomplish since your getting a custom harness and not trying to reuse a factory set up. :cheers: |
Like this one https://www.rockauto.com/en/moreinfo...sn=572&jsn=572 In case link doesn't work look up ACDELCO 3212128 |
I changed order, got 2002 CADILLAC ESCALADE 6.0L V8 ACDELCO 3351092 (335-1092) Alternator / Generator 4 wire |
Ah there you Go! |
I can breathe again. lol. I don't like ordering electrical stuff. Thanks Mike M too!! |
I had the same issue when I did my 68...... I was going to buy the 200+$ one wire alternator but did this and it works perfect.... it is very simple.... buy the plug, wire it to a 12v keyed hot and run a heavy wire from the stud on the back of the alt to your shut off switch.... then if you have issues with an alt you can run to the local Napa and get an alternator instead of having a one wire deal..... |
Makes sense. I got a nice new alternator so hopefully this one won't get burnt up. I got a 3" alternator pulley which along with my under drive pulley Capizzi said will charge 14.3 at idle and not get over spun. |

I have Summit truck SFI under drive balancer for LS and this is the overdrive alternator pulley I ordered: https://store.alternatorparts.com/24...ternators.aspx |

Im shocked if its on 24x, thats not a lot of data to tune with at those crank speeds. 58x is one data marker every 6 degrees of crank rotation vs 24x which is one data marker every 15 degrees. mean piston speed, MPS = 2 * Stroke * RPM / 60 seconds 5.3L MPS @ 8500 RPM = 2 x 3.62 ( 8500/60 ) 7.24 x 141.67 MPS = 1025.67" per second Roughly 85' per second of piston travel divided by both 24, and 58 respectively 24x = 3.6' piston travel per data point 58x = 1.4' piston travel per data point Maybe worthless info, but I was curious so I posted it up. I know if I was running a Holley system which supports 58x I would definitely want that extra data for the cost of a reluctor swap, especially if the bottom end was being opened up. Although if this is getting done on 24x maybe im wasting time here? Piston travel per crank revolution - 2 * 3.62" = 7.24" 24x = 7.24/24 = 0.302" piston travel per data point 58x = 7.24/58 = 0.125" piston travel per date point |

I think your math is a little off. 24x and 58x refer to the number of teeth on the reluctor wheel(obviously), which means that is how many teeth pass by the crank sensor every REVOLUTION, not every SECOND. The amount of piston travel per data point will not change with rpm, it will remain constant. The faster crankshaft turns, the faster the reluctor wheel turns. The math should look like this: Piston travel per crank revolution - 2 * 3.62" = 7.24" 24x = 7.24/24 = 0.302" piston travel per data point 58x = 7.24/58 = 0.125" piston travel per date point |
What do I have, not have..... Fuel pumps: Yes, Weldon 2345 and Bosch 044 are here. Fuel filters: No Fuel regulator: No Fuel line, fittings: No Co2: No Computer: No Fans for radiator: No will order when car goes back to Manna Brakes: Fronts (used) are lined up, rears are not. Hood: Lined up I need to order computer stuff and Co2 this week. "I hate money I hate money I hate money.." |
This should be my final Holley order list, thanks to Matt Bell @ Redline and others for helping: 554-102 100psi Transducer (3) 554-100 NTK WBO2 sensor (1) 558-308 Main Power Harness (1) 554-114 Dom ECM (1) 557-200 Boost Solenoids (2) 558-403 J3 Connector (1) 558-200 EV1 Injector Harness (1) 554-108 5 bar MAP (1) 558-102 24x Main Engine Harness (1) 556-128 Big Wire CNP kit w/ Coils (1) 553-106 7” TSLCD Dig Dash (1) 554-111 NOS Solenoid Driver (1) 20-149 Hi ram throttle cable bracket (1) 12-848 Fuel pressure regulator (1) |

"I hate money I hate money I hate money.." Sounds about right. regarding the alternator I too use the four pin style. I looked it up I use a 470 ohm resistor spliced into a 12v+ bat feed to excite it.. On my harness its the yellow wire iirc off the four pin plug on the back of the alt used to excite the alternator. The big single threaded rod output goes to +bat. I only use those two wires |
"I hate money" is actually not how I think, I'm the opposite. Everytime I order something over $1,000 it's an ordeal. :) In process of ordering Holley EFI (everything) and getting the brakes. Might be light at the end of the tunnel. |
https://cimg3.ibsrv.net/gimg/ls1tech...9521a0d28e.jpg Bought used hood, front Strange drag brakes, new pin on trunk lid and used Grant steering wheel, and my buddy delivered too. |

(No electronic trans for me so no Dominator). i went with Holley Dominator fuel pump tough instead of the planned magnafuel 4303. Im not missing much now! Only injectors, TB and driveshaft. oh, makes me think, what trans are you running btw? I have a strange Shaft out of my 69 Camaro, never ran, Moly, billet 1350 ends best of everything. 48.5” ctr to ctr. Never know. I need longer in the Nova. Your movin on!!! M. |
