BMW E30 M50/S50/M52/S52 wiring harness adapters

Are you planning on swapping your a  m5x or s5x motor in your e30? These harness adapters will make the swap much easier. With this simple plug-and-play adapter, you won’t have to deal with any wiring headaches. For simplicity, the harnesses use t-taps to easily connect any wires where they need to be (the number of wires vary depending on the model of your e30). The adapters are roughly 8 inches in length from the c101 to x20 connector. Any instructions that you might need will be provided. These adapters do not come with any sensors. You will need to use your own brown temperature sensor. If you have any special requests, feel free to contact us about it. If you have an older model with the square c101, you will need to provide us with your square c101. Those parts are NLA.

Options available for the m5x/s5x adapters:

- Year e30 (86-87, 87-89, 90-92)

- If 1987, does the e30 have a c104 connector in the glove box? (3 pin connector with red/green, yellow/white, and a black wire)

- Model (318i/is, 325e, 325i/is, 325ix, or m3)

- OBD1 or OBD2

- A/C
