E28 to E34 M20/M30/S38 Wiring Harness Adapter

$219.50

If you plan on swapping in a 5-Series engine from an E34 into your early E28 chassis, our plug and play harness adapters are the easiest way to go. These adapters will convert your early style “Square” C101 fusebox connector to be able to connect to the later style Round C101 harness connector from your new engine. 

• Installation Instructions included
• Extra wire for MPG
• Extra wire for Tachometer signal
• Extra wire for Vehicle Speed Signal
• Oil level sensor prewired into the adapter
• Sensors are not included

* Please leave the Model and year of your e28 (525, 535, etc...) in the notes section when placing an order.
 
Harness adapters will ship 2-3 days after your order is placed. All adapters are made to order. Because of this, neither returns nor exchanges are accepted.  All sales are final.
