Product Overview
An LS swap needs a harness built around the actual throttle, injector, MAF, alternator, PCM, and transmission combination. This harness is intended for red/blue-style compatible DBC electronics and a 4L80E, giving the builder labeled engine connections and basic chassis interface leads.
It is not for drive-by-wire or a 4L60E without modification. Confirm PCM service number, injector plugs, 3-wire MAF, one-wire alternator, transmission connector, and emissions choices.
Key Features & Performance
- Standalone harness for drive-by-cable LS/Vortec swaps
- Configured for compatible 4L80E transmission control
- EV1-style injector connection and common swap interface leads
- Provides DLC, tachometer, speedometer, park/neutral, and warning-lamp circuits in matching kits
Common Uses
- Wiring a 4L80E-controlled LS swap
- Replacing a cut or incomplete donor harness
- Moving the PCM into a custom vehicle
Technical Specifications
- Product Type: Standalone engine/transmission wiring harness
- Throttle: Drive by cable
- Transmission: 4L80E
- Engine Family: Compatible GM LS/Vortec
- Condition: New
- Replacement Type: Aftermarket
Installation & Fitment
- Lay out every branch on the engine before applying power
- Verify PCM pinout and tune compatibility
- Fuse battery and ignition feeds correctly and use clean engine/chassis grounds
- Keep harness branches away from headers and rotating parts; professional swap wiring is recommended
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Year range alone is not enough. DBW/DBC, injector style, MAF, alternator, crank/cam pattern, PCM, oxygen sensors, and transmission must all agree.
Frequently Asked Questions
Q: Will this work with a drive-by-wire throttle body? A: No. It is designed for compatible drive-by-cable setups.
Q: Is it for a 4L60E? A: No. The listed transmission is the 4L80E.
Q: Does the PCM come with the harness? A: Do not assume so; the listing identifies the harness, and a compatible programmed PCM is normally separate.
Q: Why does the PCM need tuning? A: Swap equipment, security, emissions, gearing, tire size, and transmission settings must match the finished vehicle.
