# Wiring & Fixing Load LoRA (LoraLoader)

Practical pin-by-pin connection order and common error fixes for Load LoRA (LoraLoader) in ComfyUI workflows.

## Facts (2026-10-17)

- **Target Node:** Load LoRA (LoraLoader)
- **Required Inputs:** model, clip, lora_name, strength_model, strength_clip
- **Output Pins:** MODEL, CLIP
- **Package:** Built-in Core

## Step-by-step pin wiring for Load LoRA (LoraLoader)

1. Drop [Load LoRA (LoraLoader)](https://comfy.ink/nodes/load-lora) onto the canvas by double-clicking and searching its title.
2. Connect all required upstream wires (`model, clip, lora_name, strength_model, strength_clip`) from your checkpoint loader, prompt conditioning, or image preprocessor.
3. Route the output (`MODEL, CLIP`) into your downstream [KSampler](https://comfy.ink/nodes/ksampler) or [VAE Decode](https://comfy.ink/nodes/vae-decode-encode) node, then click **Queue Prompt**.

## Fixing dependency conflicts and type mismatches

If the console prints a Python import error or tensor shape mismatch on this node, verify that your checkpoint family (SD 1.5, SDXL, or Flux) matches any attached LoRA, ControlNet, or IPAdapter weight.

For custom node packs on Windows, run **Update All** inside [ComfyUI-Manager](https://comfy.ink/nodes/comfyui-manager) or grab a fresh desktop environment from [/download](https://comfy.ink/download).

## FAQ

### Why won't a wire snap onto Load LoRA (LoraLoader)?

ComfyUI enforces strict pin types. Check that the upstream output matches `model, clip, lora_name, strength_model, strength_clip` and insert a VAE Encode/Decode or preprocessor node if converting between pixels and latents.

### How do I bypass this node temporarily without deleting my wires?

Select the node on the canvas and press **Ctrl+B** (Bypass) or **Ctrl+M** (Mute) to test your graph without disconnecting cables.
